A drawing of a graph or network diagram is a pictorial representation of the vertices and edges of a graph. This drawing should not be confused with the graph itself: very different layouts can correspond to the same graph.  In the abstract, all that matters is which pairs of vertices are connected by edges.  In the concrete, however, the arrangement of these vertices and edges within a drawing affects its understandability, usability, fabrication cost, and aesthetics.

*The [[Crossing number (graph theory)|crossing number]] of a drawing is the number of pairs of edges that cross each other.  If the graph is [[planar graph|planar]], then it is often convenient to draw it without any edge intersections; that is, in this case, a graph drawing represents a [[graph embedding]]. However, nonplanar graphs frequently arise in applications, so graph drawing algorithms must generally allow for edge crossings.<ref>{{harvtxt|Di Battista|Eades|Tamassia|Tollis|1994}}, p 14.</ref>

图的交叉数是相互交叉的边对的数目。如果图形是平面的,那么通常可以方便地画出没有任何边缘相交的图形;也就是说,在本例中,图形绘制表示嵌入图形。然而,应用中经常出现非平面图,因此图形绘制算法通常必须考虑边缘交叉。
  
 
*The [[Area (graph drawing)|area]] of a drawing is the size of its smallest [[bounding box]], relative to the closest distance between any two vertices. Drawings with smaller area are generally preferable to those with larger area, because they allow the features of the drawing to be shown at greater size and therefore more legibly. The [[aspect ratio]] of the bounding box may also be important.

一个图形的面积是它的最小边界盒的大小,相对于任意两个顶点之间的最近距离。面积小的画通常比面积大的画更可取,因为它们可以让图画的特征以更大的尺寸显示,因此更清晰。边界框的纵横比也很重要。
  
 
*Symmetry display is the problem of finding [[Graph automorphism|symmetry group]]s within a given graph, and finding a drawing that displays as much of the symmetry as possible. Some layout methods automatically lead to symmetric drawings; alternatively, some drawing methods start by finding symmetries in the input graph and using them to construct a drawing.<ref>{{harvtxt|Di Battista|Eades|Tamassia|Tollis|1994}}, p. 16.</ref>

对称显示的问题是在给定的图形中找到对称组,并找到尽可能多地显示对称的绘图。一些布局方法自动导致对称图形;另外,一些绘图方法从查找输入图形中的对称性开始,并使用它们来构造绘图。
  
 
*It is important that edges have shapes that are as simple as possible, to make it easier for the eye to follow them. In polyline drawings, the complexity of an edge may be measured by its [[Bend minimization|number of bends]], and many methods aim to provide drawings with few total bends or few bends per edge. Similarly for spline curves the complexity of an edge may be measured by the number of control points on the edge.

重要的是,边缘的形状要尽可能简单,以使眼睛更容易跟踪它们。在折线图中,一条边的复杂性可以通过它的弯曲数来衡量,许多方法的目的是提供很少的总弯曲或每条边很少弯曲的图。类似地,对于样条曲线,边的复杂性可以通过边上控制点的数量来度量。
  
 
*Several commonly used quality measures concern lengths of edges: it is generally desirable to minimize the total length of the edges as well as the maximum length of any edge. Additionally, it may be preferable for the lengths of edges to be uniform rather than highly varied.

几种常用的质量度量方法与边的长度有关:通常需要最小化边的总长度以及任何边的最大长度。此外,最好使边缘的长度一致而不是变化很大。
  
 
*[[Angular resolution (graph drawing)|Angular resolution]] is a measure of the sharpest angles in a graph drawing. If a graph has vertices with high [[degree (graph theory)|degree]] then it necessarily will have small angular resolution, but the angular resolution can be bounded below by a function of the degree.<ref name="ps09">{{harvtxt|Pach|Sharir|2009}}.</ref>

角度分辨率是图形绘制中最锐角的度量。如果一个图的顶点高度高,那么它的角分辨率就会很小,但是角分辨率可以由角的函数来限定。
  
 
*The [[slope number]] of a graph is the minimum number of distinct edge slopes needed in a drawing with straight line segment edges (allowing crossings). [[Cubic graph]]s have slope number at most four, but graphs of degree five may have unbounded slope number; it remains open whether the slope number of degree-4 graphs is bounded.<ref name="ps09"/>

*In [[force-based layout]] systems, the graph drawing software modifies an initial vertex placement by continuously moving the vertices according to a system of forces based on physical metaphors related to systems of [[spring (device)|springs]] or [[molecular mechanics]]. Typically, these systems combine attractive forces between adjacent vertices with repulsive forces between all pairs of vertices, in order to seek a layout in which edge lengths are small while vertices are well-separated. These systems may perform [[gradient descent]] based minimization of an [[energy function]], or they may translate the forces directly into velocities or accelerations for the moving vertices.<ref>{{harvtxt|Di Battista|Eades|Tamassia|Tollis|1994}}, Section 2.7, "The Force-Directed Approach", pp. 29–30, and Chapter 10, "Force-Directed Methods", pp. 303–326.</ref>

在基于力的布局系统中,图形绘制软件通过根据基于弹簧系统或分子力学的物理隐喻的力系统不断移动顶点来修改初始顶点的位置。通常,这些系统将相邻顶点之间的吸引力与所有对顶点之间的排斥力结合起来,以寻求一种边长较小而顶点分离良好的布局。这些系统可以执行梯度下降最小化的一个能量函数,或者他们可以把力直接转化为节点的速度或加速度

*Orthogonal layout methods, which allow the edges of the graph to run horizontally or vertically, parallel to the coordinate axes of the layout. These methods were originally designed for [[VLSI]] and [[Printed circuit board|PCB]] layout problems but they have also been adapted for graph drawing. They typically involve a multiphase approach in which an input graph is planarized by replacing crossing points by vertices, a topological embedding of the planarized graph is found, edge orientations are chosen to minimize bends, vertices are placed consistently with these orientations, and finally a layout compaction stage reduces the area of the drawing.<ref>{{harvtxt|Di Battista|Eades|Tamassia|Tollis|1994}}, Chapter 5, "Flow and Orthogonal Drawings", pp. 137–170; {{harv|Eiglsperger|Fekete|Klau|2001}}.</ref>

正交布局方法,允许图形的边缘水平或垂直运行,平行于布局的坐标轴。这些方法最初是为超大规模集成电路和PCB布局问题而设计的,但它们也适用于图形绘制。它们通常涉及到一种多阶段的方法,通过用顶点替换交叉点来平面化输入图,找到一个平面化图的拓扑嵌入,选择边的方向来最小化弯曲,顶点的放置始终与这些方向一致,最后一个布局压缩阶段减少
  
 
*Tree layout algorithms these show a rooted [[tree structure|tree]]-like formation, suitable for [[tree (graph theory)|trees]]. Often, in a technique called "balloon layout", the children of each node in the tree are drawn on a circle surrounding the node, with the radii of these circles diminishing at lower levels in the tree so that these circles do not overlap.<ref>{{harvtxt|Herman|Melançon|Marshall|2000}}, Section 2.2, "Traditional Layout – An Overview".</ref>

这些树布局算法显示了一种类似树的根状结构,适合树。通常,在一种称为气球布局的技术中,树中每个节点的子节点被画在围绕该节点的圆上,这些圆的半径在树的较低层次上递减,以便这些圆不会重叠。
  
 
*[[Layered graph drawing]] methods (often called Sugiyama-style drawing) are best suited for [[directed acyclic graph]]s or graphs that are nearly acyclic, such as the graphs of dependencies between modules or functions in a software system. In these methods, the nodes of the graph are arranged into horizontal layers using methods such as the [[Coffman–Graham algorithm]], in such a way that most edges go downwards from one layer to the next; after this step, the nodes within each layer are arranged in order to minimize crossings.<ref>{{harvtxt|Sugiyama|Tagawa|Toda|1981}}; {{harvtxt|Bastert|Matuszewski|2001}}; {{harvtxt|Di Battista|Eades|Tamassia|Tollis|1994}}, Chapter 9, "Layered Drawings of Digraphs", pp. 265–302.</ref>

分层图绘制方法(通常称为杉山式图)最适合于有向无环图或接近无环的图,例如软件系统中模块或函数之间的依赖关系图。在这些方法中,图的节点使用Coffman Graham算法等方法被安排到水平层中,以这样的方式,大多数边从一层向下到下一层;在这一步之后,将每一层内的节点进行排列,以最小化交叉。

Graph drawing is an area of mathematics and computer science combining methods from geometric graph theory and information visualization to derive two-dimensional depictions of graphs arising from applications such as social network analysis, cartography, linguistics, and bioinformatics.[1]

Graph drawing is an area of mathematics and computer science combining methods from geometric graph theory and information visualization to derive two-dimensional depictions of graphs arising from applications such as social network analysis, cartography, linguistics, and bioinformatics.

图形绘制是数学和计算机科学的一个交叉领域,它结合了几何图形理论和信息可视化的方法,对来自社会网络分析、制图学、语言学和生物信息学等各种应用场景进行二维描述。


A drawing of a graph or network diagram is a pictorial representation of the vertices and edges of a graph. This drawing should not be confused with the graph itself: very different layouts can correspond to the same graph.[2] In the abstract, all that matters is which pairs of vertices are connected by edges. In the concrete, however, the arrangement of these vertices and edges within a drawing affects its understandability, usability, fabrication cost, and aesthetics.[3] The problem gets worse if the graph changes over time by adding and deleting edges (dynamic graph drawing) and the goal is to preserve the user's mental map.[4]

图形或网络图的绘制是通过从图形抽象出的顶点和边表示的。这个图不应与图形本身混淆: 非常不同的图可以对应于同一个图形。抽象地说,重要的是哪一对顶点是由边连在一起。然而,在具体的绘图中,这些顶点和边的排列影响了它的可理解性、可用性、制造成本和美学。


Graphical conventions 画图公约

图2:Directed graph with arrowheads showing edge directions 带箭头显示边方向的有向图


Graphs are frequently drawn as node–link diagrams in which the vertices are represented as disks, boxes, or textual labels and the edges are represented as line segments, polylines, or curves in the Euclidean plane.[3] Node–link diagrams can be traced back to the 13th century work of Ramon Llull, who drew diagrams of this type for complete graphs in order to analyze all pairwise combinations among sets of metaphysical concepts.[5]

图经常绘制成节点链接图,其中顶点可表示为圆盘、框或文本标签,边表示为欧几里德平面上的线段、折线或曲线。节点链接图可以追溯到13世纪雷蒙 · 卢尔的作品,他为得到完全图,绘制了这种类型的图,以便分析形而上学概念集合之间的所有成对组合。


In the case of directed graphs, arrowheads form a commonly used graphical convention to show their orientation;[2] however, user studies have shown that other conventions such as tapering provide this information more effectively.[6] Upward planar drawing uses the convention that every edge is oriented from a lower vertex to a higher vertex, making arrowheads unnecessary.[7]

在有向图的情况下,箭头约定俗成的来显示它们的方向; 向上的平面绘图使用以下约定:每个边都从较低的顶点定向到较高的顶点,因此不需要箭头。


Alternative conventions to node–link diagrams include adjacency representations such as circle packings, in which vertices are represented by disjoint regions in the plane and edges are represented by adjacencies between regions; intersection representations in which vertices are represented by non-disjoint geometric objects and edges are represented by their intersections; visibility representations in which vertices are represented by regions in the plane and edges are represented by regions that have an unobstructed line of sight to each other; confluent drawings, in which edges are represented as smooth curves within mathematical train tracks; fabrics, in which nodes are represented as horizontal lines and edges as vertical lines;[8] and visualizations of the adjacency matrix of the graph.

节点链接图可被其他画图方式替代,包括邻接表示法,如圆填充,其中顶点表示为平面上不相交的区域,边表示为区域之间的邻接; 交点表示,其中顶点由非相交的几何对象表示,而边线由其交点表示;可见性表示,其中顶点由平面中的区域表示,边由彼此无障碍视线的区域表示; 汇流图,其中边表示为数学轨迹上的光滑曲线; 织物,其中顶点表示为水平线,边表示为垂直线; 以及图形邻接矩阵的可视化结点。


Quality measures 质量度量

Many different quality measures have been defined for graph drawings, in an attempt to find objective means of evaluating their aesthetics and usability.[9] In addition to guiding the choice between different layout methods for the same graph, some layout methods attempt to directly optimize these measures.

Many different quality measures have been defined for graph drawings, in an attempt to find objective means of evaluating their aesthetics and usability. In addition to guiding the choice between different layout methods for the same graph, some layout methods attempt to directly optimize these measures.

为了找到客观评价图形美观性和可用性的方法,已经定义了许多不同的图形质量度量方法。除了指导针对同一图形的不同布局方法之间的选择之外,某些布局方法还尝试直接优化这些度量。

图3:Planar graph drawn without overlapping edges 没有重叠边的平面图



  • The crossing number of a drawing is the number of pairs of edges that cross each other. If the graph is planar, then it is often convenient to draw it without any edge intersections; that is, in this case, a graph drawing represents a graph embedding. However, nonplanar graphs frequently arise in applications, so graph drawing algorithms must generally allow for edge crossings.[10]

图的交叉数是相互交叉的边对的数目。如果图形是平面的,那么通常可以方便地画出没有任何边缘相交的图形;也就是说,在本例中,图形绘制表示嵌入图形。然而,应用中经常出现非平面图,因此图形绘制算法通常必须考虑边缘交叉。

  • The area of a drawing is the size of its smallest bounding box, relative to the closest distance between any two vertices. Drawings with smaller area are generally preferable to those with larger area, because they allow the features of the drawing to be shown at greater size and therefore more legibly. The aspect ratio of the bounding box may also be important.

一个图形的面积是它的最小边界盒的大小,相对于任意两个顶点之间的最近距离。面积小的画通常比面积大的画更可取,因为它们可以让图画的特征以更大的尺寸显示,因此更清晰。边界框的纵横比也很重要。

  • Symmetry display is the problem of finding symmetry groups within a given graph, and finding a drawing that displays as much of the symmetry as possible. Some layout methods automatically lead to symmetric drawings; alternatively, some drawing methods start by finding symmetries in the input graph and using them to construct a drawing.[11]

对称显示的问题是在给定的图形中找到对称组,并找到尽可能多地显示对称的绘图。一些布局方法自动导致对称图形;另外,一些绘图方法从查找输入图形中的对称性开始,并使用它们来构造绘图。

  • It is important that edges have shapes that are as simple as possible, to make it easier for the eye to follow them. In polyline drawings, the complexity of an edge may be measured by its number of bends, and many methods aim to provide drawings with few total bends or few bends per edge. Similarly for spline curves the complexity of an edge may be measured by the number of control points on the edge.

重要的是,边缘的形状要尽可能简单,以使眼睛更容易跟踪它们。在折线图中,一条边的复杂性可以通过它的弯曲数来衡量,许多方法的目的是提供很少的总弯曲或每条边很少弯曲的图。类似地,对于样条曲线,边的复杂性可以通过边上控制点的数量来度量。

  • Several commonly used quality measures concern lengths of edges: it is generally desirable to minimize the total length of the edges as well as the maximum length of any edge. Additionally, it may be preferable for the lengths of edges to be uniform rather than highly varied.

几种常用的质量度量方法与边的长度有关:通常需要最小化边的总长度以及任何边的最大长度。此外,最好使边缘的长度一致而不是变化很大。

  • Angular resolution is a measure of the sharpest angles in a graph drawing. If a graph has vertices with high degree then it necessarily will have small angular resolution, but the angular resolution can be bounded below by a function of the degree.[12]

角度分辨率是图形绘制中最锐角的度量。如果一个图的顶点高度高,那么它的角分辨率就会很小,但是角分辨率可以由角的函数来限定。

  • The slope number of a graph is the minimum number of distinct edge slopes needed in a drawing with straight line segment edges (allowing crossings). Cubic graphs have slope number at most four, but graphs of degree five may have unbounded slope number; it remains open whether the slope number of degree-4 graphs is bounded.[12]

图的斜率数是在具有直线段边(允许交叉)的图中所需的明显边缘斜率的最小值。三次图的斜率数最多为4,五次图的斜率数可能是无界的;4度图的斜率数是否有界仍然是开放的。


Layout methods 布局方法

图4:A force-based network visualization. 基于力的网络可视化 [13]

There are many different graph layout strategies:

There are many different graph layout strategies:

有许多不同的图形布局策略:

  • In force-based layout systems, the graph drawing software modifies an initial vertex placement by continuously moving the vertices according to a system of forces based on physical metaphors related to systems of springs or molecular mechanics. Typically, these systems combine attractive forces between adjacent vertices with repulsive forces between all pairs of vertices, in order to seek a layout in which edge lengths are small while vertices are well-separated. These systems may perform gradient descent based minimization of an energy function, or they may translate the forces directly into velocities or accelerations for the moving vertices.[14]

在基于力的布局系统中,图形绘制软件通过根据基于弹簧系统或分子力学的物理隐喻的力系统不断移动顶点来修改初始顶点的位置。通常,这些系统将相邻顶点之间的吸引力与所有对顶点之间的排斥力结合起来,以寻求一种边长较小而顶点分离良好的布局。这些系统可以执行梯度下降最小化的一个能量函数,或者他们可以把力直接转化为节点的速度或加速度

频谱布局方法使用从图的邻接矩阵派生的矩阵(例如Laplacian)的特征向量作为坐标。

  • Orthogonal layout methods, which allow the edges of the graph to run horizontally or vertically, parallel to the coordinate axes of the layout. These methods were originally designed for VLSI and PCB layout problems but they have also been adapted for graph drawing. They typically involve a multiphase approach in which an input graph is planarized by replacing crossing points by vertices, a topological embedding of the planarized graph is found, edge orientations are chosen to minimize bends, vertices are placed consistently with these orientations, and finally a layout compaction stage reduces the area of the drawing.[16]

正交布局方法,允许图形的边缘水平或垂直运行,平行于布局的坐标轴。这些方法最初是为超大规模集成电路和PCB布局问题而设计的,但它们也适用于图形绘制。它们通常涉及到一种多阶段的方法,通过用顶点替换交叉点来平面化输入图,找到一个平面化图的拓扑嵌入,选择边的方向来最小化弯曲,顶点的放置始终与这些方向一致,最后一个布局压缩阶段减少

  • Tree layout algorithms these show a rooted tree-like formation, suitable for trees. Often, in a technique called "balloon layout", the children of each node in the tree are drawn on a circle surrounding the node, with the radii of these circles diminishing at lower levels in the tree so that these circles do not overlap.[17]

这些树布局算法显示了一种类似树的根状结构,适合树。通常,在一种称为气球布局的技术中,树中每个节点的子节点被画在围绕该节点的圆上,这些圆的半径在树的较低层次上递减,以便这些圆不会重叠。

  • Layered graph drawing methods (often called Sugiyama-style drawing) are best suited for directed acyclic graphs or graphs that are nearly acyclic, such as the graphs of dependencies between modules or functions in a software system. In these methods, the nodes of the graph are arranged into horizontal layers using methods such as the Coffman–Graham algorithm, in such a way that most edges go downwards from one layer to the next; after this step, the nodes within each layer are arranged in order to minimize crossings.[18]

分层图绘制方法(通常称为杉山式图)最适合于有向无环图或接近无环的图,例如软件系统中模块或函数之间的依赖关系图。在这些方法中,图的节点使用Coffman Graham算法等方法被安排到水平层中,以这样的方式,大多数边从一层向下到下一层;在这一步之后,将每一层内的节点进行排列,以最小化交叉。

图5:Arc diagram 弧线图


  • Arc diagrams, a layout style dating back to the 1960s,[19] place vertices on a line; edges may be drawn as semicircles above or below the line, or as smooth curves linked together from multiple semicircles.

弧图,一种布局风格可以追溯到20世纪60年代,将顶点放在一条直线上;边缘可以画成在直线上方或下方的半圆,也可以画成由多个半圆连接在一起的光滑曲线。

  • Circular layout methods place the vertices of the graph on a circle, choosing carefully the ordering of the vertices around the circle to reduce crossings and place adjacent vertices close to each other. Edges may be drawn either as chords of the circle or as arcs inside or outside of the circle. In some cases, multiple circles may be used.[20]

圆形布局方法将图形的顶点放置在一个圆上,仔细选择圆周上顶点的顺序,以减少交叉,并将相邻的顶点放置在彼此接近的位置。边可以画成圆的弦,也可以画成圆内外的弧线。在某些情况下,可以使用多个圆。

  • Dominance drawing places vertices in such a way that one vertex is upwards, rightwards, or both of another if and only if it is reachable from the other vertex. In this way, the layout style makes the reachability relation of the graph visually apparent.[21]

当且仅当一个顶点可以从另一个顶点到达时,优势画顶点的方式是:一个顶点向上,或向右,或两个顶点同时向上。这样,布局风格使得图的可达性关系在视觉上变得明显。

In addition, the placement and routing steps of electronic design automation (EDA) are similar in many ways to graph drawing, as is the problem of greedy embedding in distributed computing, and the graph drawing literature includes several results borrowed from the EDA literature. However, these problems also differ in several important ways: for instance, in EDA, area minimization and signal length are more important than aesthetics, and the routing problem in EDA may have more than two terminals per net while the analogous problem in graph drawing generally only involves pairs of vertices for each edge.

此外,电子设计自动化(EDA)的布局和布线步骤在很多方面与图形绘制相似,而在分布式计算中贪婪嵌入的问题也是如此,并且图形绘制文献包括从EDA文献中借来的一些结果。然而,这些问题也在几个重要方面有所不同: 例如,在 EDA,面积最小化和信号长度比美观更重要,EDA中的路由问题可能每个网有两个以上的终端,而图绘制中的类似问题通常只涉及每条边的顶点对。
