This is fantastic. I'm planning to build something similar in the coming months.<p>Only minor nit pick, not the easiest to read on mobile<p><a href="http://m.imgur.com/Uloatup.jpg" rel="nofollow">http://m.imgur.com/Uloatup.jpg</a>
Very cool! Dc.js is a very powerful and quick way to build interactive crossfiltered charts.<p>At MapD we built our own visualization frontend using Dc.js as a base, except we leverage GPUs on the backend both for SQL and rendering data. The upshot is we can scale to multi-billion row datasets with millisecond response times.<p>You can see an example with 200M streaming geocoded tweets here - <a href="https://www.mapd.com/demos/tweetmap" rel="nofollow">https://www.mapd.com/demos/tweetmap</a>.
Awesome! The GIF is great but would really love a link to a live demo to play with :)<p>Didn't know could do heatmap via leaflet - does it respond to crossfilter filtering?
