Interactive Data Visualization of Geospatial Data

This is fantastic. I'm planning to build something similar in the coming months.

Only minor nit pick, not the easiest to read on mobile

Thanks for the feedback! I will fix it.

Very cool! Dc.js is a very powerful and quick way to build interactive crossfiltered charts.

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.

You can see an example with 200M streaming geocoded tweets here - https://www.mapd.com/demos/tweetmap.

Awesome! The GIF is great but would really love a link to a live demo to play with :)

Didn't know could do heatmap via leaflet - does it respond to crossfilter filtering?
