I'd still love to see a graphviz equivalent for JS that does layout for digraphs. This looks cool if you need undirected graphs, but doesn't seem to have any digraph support.
I have never used it, but vis.js supports the DOT language.

Try https://github.com/cpettitt/dagre , it's using some of the latest and most performant algos, really nice + a D3 renderer.

Sigma is significantly faster than D3 for drawing large graphs; however, it's only able to draw graphs. D3 is a multipurpose library for many different kinds of visualizations.
Are you comparing Sigma with using D3 with SVG? One could also use a canvas to make it render faster.

#24Looks great, but I think it would benefit a lot from more examples. :)
You can check the examples in the repository: https://github.com/jacomyal/sigma.js/wiki#wiki-getting-start...
I know it's pretty simple to run the examples yourself, but it would be nice if they were hosted on sigmajs.org. Great work, though. Pretty sure I'm going to try this today or tomorrow.

The library that I make, GoJS (http://www.gojs.net/) has a tree layout and layered digraph layout, both with many options.
Here's an overview of the options for the layered digraph layout: http://www.gojs.net/latest/samples/ldLayout.html
The tree layout supports some fairly complicated tree structures, including ones that alternate or have different configurations for leaves: http://www.gojs.net/latest/samples/tLayout.html
Disclosure: I'm a developer of this library and it is not free.

I keep this in mind. We need to find an easy way to export examples formatted with the good template etc... before putting anything public, to ensure it's not too hard to update the production server when we release sigma.js.

#28What are the strengths of this library, relative to D3? How does Sigma work differently?
On the technical side: D3 is built on svg, looks like this is built on canvas. There are a few implications to both of those as far as compatibility and performance, but shouldn't make a difference in most cases.
In general, D3 looks to be a more general purpose graphing tool (also maps, multiple charting types, and graphs), while this is more single purpose.

#29I've used both Sigma.js and Arbor.js (http://arborjs.org/) extensively. I liked Arbor a bit better for smaller graphs, because of its flexible API and separated drawing and math components. Unfortunately Arbor seems abandoned by the author last updates were two years ago), so i guess Sigma might be a better choice right now.

Also commercial with digraph layout functionality:
