ngraph.gexf

Gephi gexf file parser for server and browser. This library is a part of ngraph project. See demo here: Talking with Gephi

usage

This library allows you to load gexf files into ngraph.graph.

var fs = require('fs');
var gexf = require('ngraph.gexf');
var graph = gexf.load(fs.readFileSync('myfile.gexf', 'utf8'));
// graph is now normal grpah and can be used by ngraph modules

You can also store graph into gexf file format:

var gexf = require('ngraph.gexf');

var binTree = require('ngraph.generators').balancedBinTree(5);
var gexfFileContent = gexf.save(binTree);

Details

This library supports node.js and browser runtime (via browserify). When used from node.js it uses libxmljs library for quick parsing of xml files. When used in a browser it uses browser's capabilities to read and query xml files.

Because of this, library size is really small when served in the browser:

• 24kb - unminified
• 13kb - minified
• 4kb - gzipped

Current implementation is really basic and does not support some of the gexf features:

• Dynamics - https://gephi.org/gexf/format/dynamics.html
• Hierarchy - https://gephi.org/gexf/format/hierarchy.html
• Phylogeny - https://gephi.org/gexf/format/phylogeny.html

Adding Hierarchy and Phylogeny is relatively easy and they will be implemented if such need arise. Dynamics - requires to think a little bit to better represent graph's timeline.

install

With npm do:

npm install ngraph.gexf
