European word translator

I'm a big fan of the etymology maps on reddit. These gave me the idea of creating a map that would translate any English word (or two) to other European languages using Google Translate. The results are often far from perfect - the screenshot below shows that "a bug in a rug" becomes "an error in a rug" in Spanish. This may be partly because Google Translate has little context to work with when only one or two words are entered, and partly because it just isn't as smart as a human translator. Still, hopefully it's fun to play with!

Treemaps of emissions and Reddit posts


A couple of my recent experiments have been treemap visualisations using D3. Treemaps are useful for showing part-to-whole relationships when there are many data points and the data points can be categorised (countries by continent, stocks by sector and sub-sector etc). The Map of the Market is a nice example.

The interactive treemap I created of emissions and population is shown below. I think it does a reasonable job of showing the data, but perhaps it could be improved by dividing the countries into categories such as continents. I also wonder if side-by-side bar charts might be a simpler better way to show the data.

My other treemap shows the top 200 reddit posts of all time. It's just a bit of fun, but I'm not sure if it's really a successful visualisation; to me, the design of a treemap implies the relationship of parts to a whole, but in this treemap "the whole" is arbitrarily chosen to be only the top 200 posts.
