'''Graph Modeling Language''' (GML) is a hierarchical [[ASCII]]-based file format for describing [[Graph (discrete mathematics)|graphs]]. It has been also named ''Graph Meta Language''.<br />
<br />
==Example==<br />
A simple graph in GML format:<br />
<pre><br />
graph [<br />
comment "This is a sample graph"<br />
directed 1<br />
id 42<br />
label "Hello, I am a graph"<br />
node [<br />
id 1<br />
label "node 1"<br />
thisIsASampleAttribute 42<br />
]<br />
node [<br />
id 2<br />
label "node 2"<br />
thisIsASampleAttribute 43<br />
]<br />
node [<br />
id 3<br />
label "node 3"<br />
thisIsASampleAttribute 44<br />
]<br />
edge [<br />
source 1<br />
target 2<br />
label "Edge from node 1 to node 2"<br />
]<br />
edge [<br />
source 2<br />
target 3<br />
label "Edge from node 2 to node 3"<br />
]<br />
edge [<br />
source 3<br />
target 1<br />
label "Edge from node 3 to node 1"<br />
]<br />

== Applications supporting GML==<br />
* [[Cytoscape]], an [[Open-source license|open source]] [[List of bioinformatics software|bioinformatics software]] platform for visualizing molecular interaction networks, loads and save previously-constructed interaction networks in GML.<br />
* [[igraph]], an [[Open-source license|open source]] network analysis library with interfaces to multiple programming languages.<br />
* [[Gephi]], an [[Open-source license|open source]] graph visualization and manipulation software.<br />
* [[Graph-tool]], a [[Free software|free]] Python module for manipulation and statistical analysis of graphs.<br />
* [[NetworkX]], an [[Open-source license|open source]] [[Python (programming language)|Python]] library for studying complex graphs.<br />
* [[Tulip (software)]] is a free software in the domain of [[information visualisation]] capable of manipulating huge graphs (with more than 1.000.000 elements).<br />
* [[yEd]], a free Java-based graph editor, supports import from and export to GML.<br />
* The [[Graphviz]] project includes two command-line tools (gml2gv and gv2gml) that can convert to and from the [[DOT_(graph_description_language)|DOT]] file format.<br />
* [[Wolfram Language]], a general very high-level programming language, supports [https://reference.wolfram.com/language/ref/format/Graphlet.html GML import and export].<br />
