It's a framework around D3, if you want to see what the charts will look like , you can see them on the D3 site.
From all the beautiful graphs present on the D3 site, the demo shows some boring examples. Why not dazzle the audience with a force-directed layout?
So if there's no differentiator why should I be interested in it? If you have a library that's entire purpose is visual and you show me nothing then that's a failure. I'm not going to clone a repo and spin up some examples just to see if they suck or are awesome.
indeed, first thought was how does it differ from classic d3 charts ? i like d3 a lot, but usually it takes some boilerplate code to setup charts. when working with multiple datasets the d3 commands look a bit confusing at times, so higher level abstractions are interesting to see
