How to Make a Heatmap – a Quick and Easy Solution
A heatmap is a literal way of visualizing a table of numbers, where you substitute the numbers with colored cells. This is a quick way to make one in R. A heatmap is basically a table that has colors in place of numbers. Colors correspond to the level of the measurement. Each column can be a different metric like above, or it can be all the same like this one. It’s useful for finding highs and low
Famous Movie Quotes as Charts →
In celebration of their 100-year anniversary, the American Film Institute selected the 100 most memorable quotes from American cinema, and a few years ago, for kicks and giggles, I put the first eight quotes into chart form. I planned to chartify all 100, but I got distracted. Lately though, finishing what I started became my distraction. So here it is: the 100 most memorable quotes in chart form
The Best Data Visualization Projects of 2011
I almost didn’t make a best-of list this year, but as I clicked through the year’s post, it was hard not to. If last year (and maybe the year before) was the year of the gigantic graphic, this was the year of big data. Or maybe we’ve gotten better at filtering to the good stuff. (Fancy that.)

Language communities of Twitter
Eric Fischer maps language communities on Twitter using Chrome’s open-source language detector. Each color, chosen to make differences more visibly obvious, represents a language. English is represented in dark gray, which is used just about everywhere, so it doesn’t obscure everything else. The emergence of borders without actually drawing them in is interesting. There’s a little bit of blending,
GeoCommons 2.0, now with more mapping features
GeoCommons, an open repository of data and maps, launched version 2.0 this week, which is more feature-rich and robust than the first. Two of the major updates have to do with the fast-changing data landscape: amount of data and browser technology. In this new version, you can load tens of thousands of points no problem, whereas in the previous version, the application grew sluggish. If you’ve use
