Orange: Network .gml
GML (Graph Modeling Language) is a text file format supporting network data with a very easy syntax. It is used by Graphlet, Pajek, yEd, LEDA and NetworkX. GML Specification Official GML Specification
Gephi currently doesn’t provide a complete support of the GML format. Data structures are not supported. Datasets
Mark Newman’s page provides a large range of networks in GML here. Examples
The sample below shows a graph of three nodes and two edges.
graph [ node [ id A ] node [ id B ] node [ id C ] edge [ source B target A ] edge [ source C target A ] ]
The sample below shows the same example but with both node and edge labels.
graph [ node [ id A label "Node A" ] node [ id B label "Node B" ] node [ id C label "Node C" ] edge [ source B target A label "Edge B to A" ] edge [ source C target A label "Edge C to A" ] ]
