Types of Charts. There are several different types of charts and graphs. The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs. They are generally used for, and best for, quite different things.
The former type of graph is called an undirected graph and the edges are called undirected edges while the latter type of graph is called a directed graph and the edges are called directed edges. Graphs are the basic subject studied by graph theory. The word graph was first used in this sense by J. J. Sylvester in 1878.
