At last October’s NACIS Practical Cartography Day I gave a very sweaty presentation that was later described as bewildering and incoherent. I had always meant to partially redeem myself by packaging and cleaning up the code that formed the basis of that talk. And here it is!

In this post I’m only talking about spatial (long-lat) and 2-dimensional attribute-based (scatterplot) bins. Such binnings may be thought of as 2D histograms. This [...]

OpenLayers has been around a while, but still performs remarkably well as a slippy map framework while allowing easy thematic map customization. Polymaps is [...]
