DOT language

DOT is a plain text graph description language. It is a simple way of describing graphs that both humans and computer programs can use. DOT graphs are typically files that end with the .dot extension. Various programs exist to process DOT files. These programs can read DOT files and render them, or provide an interface to manipulate the graphs. One such program, dot, is used by the source code documentation generator doxygen. dot is part of the G... more

DOT is a plain text graph description language. It is a simple way of describing graphs that both humans and computer programs can use. DOT graphs are typically files that end with the .dot extension. Various programs exist to process DOT files. These programs can read DOT files and render them, or provide an interface to manipulate the graphs. One such program, dot, is used by the source code documentation generator doxygen. dot is part of the Graphviz package. At its simplest, DOT can be used to describe an undirected graph. An undirected graph shows simple relations between objects, such as friendship between people. The graph keyword is used to begin a new graph, and nodes are described within curly braces. A double-hyphen (--) is used to show relations between the nodes. Similar to undirected graphs, DOT can describe directed graphs, such as flowcharts and dependency trees. The syntax is the same as for undirected graphs, except the digraph keyword is used to begin the graph, and... less
