In node.js method getBBox is missing.

[petrounias]

Attempting to run the renderer in node.js results in the following error:

TypeError: Object [ G.node.enter ] has no method 'getBBox'

due to the following line in Renderer.js:

var bbox = root.node().getBBox();

What DOM are you using in node.js? If you are trying to run a layout algorithm without a DOM, dagre (versus dagre-d3) would be the way to go.

I am using jsdom. I have verified I can output SVG's just fine (e.g. adding a simple circle to the svg element, and so on) - it's only the missing getBBox method that's the problem.

Take a look at this comment from Mike Bostock (author of D3). He says that jsdom doesn't have proper SVG support and recommends using PhantomJS. I have personally used PhantomJS with dagre-d3 in the past. See https://github.com/cpettitt/dagre-d3-cli as a proof-of-concept example.

Can confirm that the renderer works with PhantomJS and not jsdom, both within a node.js context and standalone. May I suggest a comment in the documentation stating that getBBox is only available in PhantomJS as far as we know for now? Thanks for your time!
