DOT (.gv, .dot)

  • Import and Export fully support the DOT format.
  • Background

      DOT graph language and data format.
      Commonly used exchange format for graphs.
      Stores a single attributed, directed, or undirected graph.
      Can contain user-defined graph, edge, and vertex attributes.
      Plain text format.
      Developed by AT&T Bell Laboratories.

    Import and Export

    • Import["file.gv"] gives a Graph object representing the graph stored in the specified file.
    • Export["file.gv",expr] exports an adjacency matrix or edge information representing a graph to the DOT format.
    • Import["file.gv"] imports the graph from file and returns it as a Graph.
    • Import["file.gv",elem] imports the specified element from a DOT file.
    • Import["file.gv",{{elem1,elem2,}}] imports multiple elements.
    • The import format can be specified with Import["file","DOT"] or Import["file",{"DOT",elem,}].
    • Export["file.gv",expr,elem] creates a DOT file by treating expr as specifying element elem.
    • Export["file.gv",{expr1,expr2,},{{elem1,elem2,}}] treats each expri as specifying the corresponding elemi.
    • Export["file.gv",expr,opt1->val1,] exports expr with the specified option elements taken to have the specified values.
    • Export["file.gv",{elem1->expr1,elem2->expr2,},"Rules"] uses rules to specify the elements to be exported.
    • See the reference pages for full general information on Import and Export.
    • ImportString and ExportString support the DOT file format.

    Elements

    • General Import elements:
    • "Elements"list of elements and options available in this file
      "Rules"full list of rules for each element and option
      "Options"list of rules for options, properties, and settings
    • Data representation elements:
    • "AdjacencyMatrix"edge information, given as a matrix
      "EdgeAttributes"edge attributes, represented as a list of rules
      "EdgeRules"connectivity data for the graph, given as a list of rules
      "Graph"graph stored in the file, given as a Graph object
      "GraphAttributes"graph attributes, represented as a list of rules
      "Graphics"graph stored in the file, rendered as a graph plot
      "VertexAttributes"vertex attributes, represented as a list of rules
      "VertexCount"number of vertices in the graph
      "VertexList"vertices, given as a list of strings
    • Import by default uses the "Graph" element when importing from DOT.
