An alternative representation of the hypergraph called PAOH<ref name="paoh" /> is shown in the figure on top of this article. Edges are vertical lines connecting vertices. Vertices are aligned on the left. The legend on the right shows the names of the edges. It has been designed for dynamic hypergraphs but can be used for simple hypergraphs as well.

超图的另一种表示法被称做 PAOH[24]，如上图所示，边是连接顶点的垂线，顶点在左边是对齐的。右边的图例显示了边的名称。它是为动态超图设计的，但也可以用于简单的超图。
