TGF (.tgf)

TGF graph data format.
Used for the storage and exchange of graphs.
TGF is an acronym for Trivial Graph Format.
Stores directed graphs.
Stores at most one label per vertex and edge.
ASCII format.
  • Import imports the graph stored in the specified file, given as a single Graph object.
  • Export exports an adjacency matrix or edge information for one graph to the TGF format.
  • Import imports the specified element from a TGF file.
  • Import imports multiple elements.
  • Export creates a TGF file by treating expr as specifying element elem.
  • Export treats each as specifying the corresponding .
  • Export exports expr with the specified option elements taken to have the specified values.
  • Export uses rules to specify the elements to be exported.
  • See the reference pages for full general information on Import and Export.
"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, rendered as a Graph object
"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 element when importing from TGF.
ImageSizeAutomaticspecifies the overall size of the image to display for a graph
  • When importing from a TGF file, all options supported by Graph can be given. Common settings include:
EdgeLabelsAutomaticlabels and label placement for edge
EdgeWeightAutomaticweight for edge
VertexCoordinatesAutomaticcenter coordinate for vertex
VertexLabelsAutomaticlabels and label placement for vertex
VertexShapeAutomaticgraphic shape for vertex
  • When importing , all options supported by GraphPlot can be given. Common settings include:
DirectedEdgesAutomaticwhether to show edges as directed arrows
EdgeLabelingAutomaticwhether to include labels given for edges
EdgeRenderingFunctionAutomaticfunction to give explicit graphics for edges
VertexLabelingAutomaticwhether to show vertex names as labels
VertexRenderingFunctionAutomaticfunction to give explicit graphics for vertices
