High Performance JS heatmaps

High Performance JS heatmaps by Florian Boesch. (live demo)

From the webpage:

You might have encountered heatmaps for data visualization before. There is a fabulous library, heatmap.js, which brings that capability to draw them to javascript. There is only one problem, it is not exactly fast. Sometimes that doesn’t matter. But if you have hundreds of thousands of data points to plot, or need realtime performance, it gets tricky. To solve that I’ve written a little engine using WebGL for drawing heatmaps.

Github: WebGL Heatmap.

Another tool for your data visualization toolkit.

I first saw this in Nat Torkington’s Four Short Links: 18 March 2013.

GraphGL, network visualization with WebGL

GraphGL, network visualization with WebGL.

From the introduction:

GraphGL is a network visualization library designed for rendering (massive) graphs in web browsers and puts dynamic graph exploration on the web another step forward. In short, it calculates the layout of the graph in real time and is therefore suitable for static files (exported GraphML/GEXF files) and for dynamic files (LinkedIn InMaps would be one such example).

As such, it is both a replacement for Gephi and a complimentary tool, similar to Seadragon, providing another method for displaying graphs in a Web browser.

A very good article that also covers technical issues of graph rendering in a web context.

A project to watch, or better yet, to help advance.
