It's functionally very close to https://colorbrewer2.org , which has been online for more than 15 years. I think it's not a coincidence, and some credits wouldn't have hurt anyone... Also, I have personally been us

FYI there is indeed a strong demand, and having the ability to develop full-stacked web apps is a nice plus as well. You can check this Google Group[0] to see actual requests (full-time jobs, part-time jobs and limited prestations). [0] ht

Both are really different. Phantom.js is a headless browser while artoo is a tool to easily scrape data from website. But combining both would be nice to make it possible to automatize scrapers that have been developed quickly directly in t

Basically, it makes scraping accessible to almost anyone who can use a browser and write some CSS selectors.

That is weird, indeed. The thickness of the edges should be related to their "size" value. After that, check how sigma rescales the nodes and edges in the related wiki page: https://github.com/jacomyal/sigma.j

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.

It is one hard part. But displaying thousands of elements in a web page is another one. Also, sigma does provide in a plugin a force-directed layout, ForceAtlas2, initially developed for Gephi.

Actually, as with d3, you can develop your own network visualization layouts. The main difference is that sigma only deals with graphs drawing, so it deals without effort with drag and drop (mouse or touch), scaling the graph to the screen,

First, the canvas element does not work everywhere ( http://caniuse.com/canvas ). Also, canvas is faster in Chrome. For instance, here is one benchmark about layered canvases (sigma.js actually layers different canvases): http://jsperf.com

I am formerly a big fan and user of Gephi, so I think graph drawing is "important enough" to deserve its own JavaScript library, which is why I made sigma.js. I know d3.js is already a great tool, but it looked hardcore for me to tweak it t
