net-to-img
A CLI tool and library to quickly render a network's topology as an image. Its goal is to make it easy to visually detect some graph patterns (stars for instance).
Installation
npm install --global net-to-img
Usage
At the moment, net-to-img
only supports GraphML, GEXF and JSON for Graphology formats, and only writes images as PNG images:
net-to-img path/to/graph/file path/to/output/image
To see the list of all options, run:
net-to-img --help# or netimg --help
Library usage
You can also use net-to-img
programmatically if you need to:
const netToImg = ; ; // To directly pass a graph instance; // Directly passing string data;
Disclaimer
This tool has been developped quite quickly (thanks for all the job previously done in the Graphology environment by Guillaume Plique), and it breaks very easily, on a lot of the graph files I tried it on. It could be improved, especially around the following issues:
- Errors management
Stronger GraphML parserLouvain multi-graph supportAuto sizes for nodes- More graph formats (GML,
JSON...) - More image formats (JPG,
SVG...) - ...
