Load dot files into ngraph.graph

ngraph.fromdot

Load dot files into ngraph.graph

usage

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 2

ngraph.fromdot's Issues

attributes/value not loaded from dot

I noticed that only the structure of a .dot file is loaded into the graph, and not the data attributes/values.
In the source there's a TODO confirming that. (also in the todot module node attributes weren't written out either)

any chance of you ticking that TODO of your list?

or in the meantime, any suggestions for storing(serializing) a graph and its values in txt format?
I don't particularly care for the .dot format, I have a graph generated via your library which I need to load into your library somewhere else.

thanks!

Multigraph support broken

I believe v20 of nGraph and its changes to how addLink handles multiGraphs has broken this module.
