Heat Maps Catch on Fire

Zillow’s got ’em. So does Trulia. Crazy Egg will even map your web site activity with them. Basically, any data set can be made visually sexier with a heatmap.

That said, the GeoIQ API renders some of the best looking heat maps that I’ve seen so far. Check out their API Example.

I suspect we’ll be seeing more and more heat map implementations come to market very soon; housing prices, rental prices, cost of living, census data, weather trends, financial data – all can be displayed via a heat map. Consolidating this complex information into a visual representation highlights subtle patterns and illustrates trends very effectively.

Plus it just looks cool (or hot).
