Graph drawing
As a branch of graph theory, Graph drawing applies topology and geometry to derive two- and three-dimensional representations of graphs. Graph drawing is motivated by applications such as VLSI circuit design, social network analysis, cartography, and bioinformatics. Graphs are usually represented pictorially using dots to represent vertices, and arcs to represent the edges between connected vertices. Arrows can be used to show the orientation of directed edges. Note that this graphical representation (a graph layout or an embedding) should not be confused with the graph itself (the abstract, non-graphical structure).
