Graph Modelling Language
Graph Modeling Language (GML) is a hierarchical ASCII-based file format for describing graphs. It has been also named Graph Meta Language.
Example[edit]
A simple graph in GML format:
graph [
comment "This is a sample graph"
directed 1
id n42
label "Hello, I am a graph"
node [
id 1
label "node 1"
thisIsASampleAttribute 42
]
node [
id 2
label "node 2"
thisIsASampleAttribute 43
]
node [
id 3
label "node 3"
thisIsASampleAttribute 44
]
edge [
source 1
target 2
label "Edge from node 1 to node 2"
]
edge [
source 2
target 3
label "Edge from node 2 to node 3"
]
edge [
source 3
target 1
label "Edge from node 3 to node 1"
]
]
Applications supporting GML[edit]
- Cytoscape, an open source bioinformatics software platform for visualizing molecular interaction networks, loads and save previously-constructed interaction networks in GML.
- Gephi, an open source graph visualization and manipulation software.
- Graph-tool, a free and efficient Python module for manipulation and statistical analysis of graphs.
- NetworkX, an open source Python library for studying complex graphs.
- Tulip (software) is a free software in the domain of information visualisation capable of manipulating huge graphs (with more than 1.000.000 elements).
- yEd, a free Java-based graph editor, supports import from and export to GML.
