Color coding

Definition

Color coding is a technique used in graph drawing algorithms to assign colors to the elements of a graph, such as vertices or edges, in a way that helps in visualizing and understanding the structure of the graph. This method simplifies complex data and aids in distinguishing between different components, enhancing clarity and interpretation during analysis.
