I don't like to be THAT guy on HN who posts off-topic criticism (especially on a really interesting link like this), but as someone who is very interested in data visualization I think it's worth pointing out: pie charts are almost never the correct way to visualize data. I decided to mention this because it's not really intuitive - even many data vis experts had to be taught this. A bar chart presents the same information and is better in almost every way.
Both your pie charts are a good example of how useful information is lost when you have more than a few categories. Both also make it hard to compare the relative magnitudes of smaller categories.

- gus_massa 13y agoA possible way of not been that guy is providing a better visualization. I downloaded the data and tried to do a better graph, but I think I failed :( . http://imgur.com/a/HEcFu http://imgur.com/a/HEcFu In the linear graph, the size of the U.S. column is so big that makes the sizes of the other countries difficult to see. In the logarithmic graph () the sizes are too deformed, so it doesn't look good neither. (() Is it even legal to use a logarithmic scale with percents??)
