The command line tool "gml2gv" is used to convert Graph Modeling Language (GML) files into Graphviz's DOT format. GML is a textual representation for describing graph structures, while DOT is a graph description language used by Graphviz, a popular graph visualization software.
The gml2gv tool allows users to convert GML files, which can represent complex graphs with nodes and edges, into a format that can be easily visualized using Graphviz. This tool is particularly helpful when you want to generate visual representations of graphs created in GML and integrate them into presentations, reports, or any other visualization contexts supported by Graphviz.
By leveraging gml2gv, you can automate the conversion process and efficiently generate graph visualizations without having to manually create DOT files or go through intermediate steps. The resulting DOT files can then be processed by Graphviz to create various types of graph visualizations like directed or undirected graphs, trees, clusters, and more.
Overall, gml2gv simplifies the process of converting GML files into a format compatible with Graphviz, enabling you to visualize and analyze complex graph structures easily.
