DOT (filename.dot) is a file format to draw graphs including directed graphs.

DOT writes graphs in .ps, .pdf, .gif, .png formats.

For example,

$ dot -Tps src.dot -o dest.ps

$ dot -Tpdf src.dot -o dest.pdf

Dot file format is as follows:

digraph graphName {

"Node 1" -> "Node 2" ;

"Node 1" -> "Node 2" -> "Node 3";

}

Each line is terminated by semicolon (;), and arrow (->) is used to show directed arc.

digraph means directed graph whereas graph means undirected graph.

Within a main graph a subgraph define a subset of graph.

For example,

digraph GraphName {

"Node 1" -> "Node 2";

subgraph SubGraphName{

"Node 3" -> "Node 1";

"Node 4" -> Node 3";

}

}
