Load dot files into ngraph.graph
You can get the library from CDN:
<script src='https://cdn.jsdelivr.net/npm/ngraph.fromdot/dist/ngraph.fromDot.js'></script>Or from npm:
npm install ngraph.fromdot
and then:
var fromDot = require('ngraph.fromdot');After the library is loaded, it is straightforward to use:
// you can load empty graph:
var emptyGraph = fromDot('digraph G {}');
// or graph with edges only:
var twoEdgesGraph = fromDot('digraph G { a -> b }');
// above graph is the same as
var sameAsAbove = fromDot('digraph G { a; b; a -> b }');
// you can also "append" to existing graph if you wish so:
fromDot('digraph B { a -> b }', emptyGraph);
// now emptyGraph is no longer empty:
emptyGraph.getLinksCount(); // returns 1
emptyGraph.getNodesCount(); // returns 2MIT
