D3-dag – Layout algorithms for visualizing directed acylic graphs
I recently wanted to render some graphs and found there are a confusing variety of options.  In particular <a href="https://github.com/dagrejs/dagre/wiki" rel="nofollow">https://github.com/dagrejs/dagre/wiki</a> seems to be layout focused and then plugs into a bunch of other systems including d3.  It would be nice if one of these tools was able to describe itself in contrast to the others.
