As cool as it looks, its almost impossible to get the finer details with these kinds of visualizations.

For example, India apparently exports 10m worth of arms. To find out which countries buy from India is nearly impossible because of the relative scale of the visualization.

Below is a link to an image from the SIPRI db about countries India exports to. The database they used is pretty easy to use if you want to go more in depth.

You can always google specific information, but visualisations like these help to tell the whole story.
