Data gathering and processing requires access to data and has several inherent issues, including [[information overload]] and data errors. Once data is collected, it will need to be transformed into a format that can be effectively used by both human and computer analyzers. Manual or computer-generated visualizations tools may be mapped from the data, including network charts. Several algorithms exist to help with analysis of data – [[Dijkstra's algorithm|Dijkstra’s algorithm]], [[breadth-first search]], and [[depth-first search]]. | Data gathering and processing requires access to data and has several inherent issues, including [[information overload]] and data errors.
