Aren't treemaps most useful when there's a hierarchical relationship. What's the structure here? Feels like a bar chart would have been better.

Maybe more useful if hierarchical relationships exist but I just love treemaps in general. I love the way they can make the most of that given screen space. A bar chart would not be able to fit in that screen area because there has to be empty space in a bar chart.

Still good for proportionality. Would’ve been even cooler though with folders for EU, NATO, and other groups that I’m ignorant of. Spacesniffer-style.
