DOT is a simple text-based file format for storing a single undirected or directed graph.

It also allows the application of attributes to nodes, edges and graphs.

The GraphTheory[ImportGraph] and GraphTheory[ExportGraph] commands can read from and write to this format.

The general-purpose commands Import and Export also support this format.

$G≔\mathrm{Import}\left(''example/digraph.dot''\,\mathrm{base}=\mathrm{datadir}\right)$

$G≔\mathrm{Graph\; 1:\; a\; directed\; graph\; with\; 11\; vertices\; and\; 12\; arc(s)}$

$\mathrm{DrawGraph}\left(G\,\mathrm{style}=\mathrm{spring}\right)$

$\mathrm{DG}≔\mathrm{GraphTheory}:-\mathrm{SpecialGraphs}:-\mathrm{DesarguesGraph}\left(\right)$

$\mathrm{DG}≔\mathrm{Graph\; 2:\; an\; undirected\; graph\; with\; 20\; vertices\; and\; 30\; edge(s)}$

$\mathrm{Export}\left(''desargues.dot''\,\mathrm{DG}\,\mathrm{base}=\mathrm{homedir}\right)$
