sigma.js - Sigma graph not displaying, but no error message -


i'm trying make poc using http://sigmajs.org/ on gexf data generated https://github.com/splitbrain/dokuwiki-grapher/.

the attempt here, not displaying anything: http://galerie.microalg.info/profgra.html

anyone please?

that's because nodes don't have size or position.
can loop on nodes , give them need so:

sigma.parsers.gexf(   'profgra.gexf',   { container: 'graph-container' },   // executed after graph loading:   function(sigmainstance) {     sigmainstance.graph.nodes().foreach(function(node, i, a) {       // on circle:       node.x = math.cos(math.pi * 2 * / a.length);       node.y = math.sin(math.pi * 2 * / a.length);       // default size:       node.size = 1;     });     sigmainstance.refresh();   } );
