I also find the graphics to be a little bit difficult to read.

It is hard to tell where the lines lead, so I need to rotate the globe. Also for European nations, it is very messy because some of the countries are tiny and all trade with each other. There is also no way to see arms trade over time, which would have been quite useful since the data has a time-series.

Very pretty looking 3D graphic though.

It is hard to read and some delay when moving around for me also.

It is nice as a demonstration on how the web may look like in 3 years, but personally I prefer tables and graphs when viewing statistics. Has anyone seen a link to a “classic” view?

I wanted to recommend the option of disabling the country labels when zooming in, at least the labels of those countries that are not selected. But apparently the OP is not the original author of the tool.
