This is what I was expecting honestly. I assume a good chunk to America, another chunk to other countries with "2nd Ammendment" like rights, or at least where it's legal to own guns for hunting.

Edit: Another interesting bit of information would show which guns by type, company, how many they create and what have you.

The visualization is driven by the Stockholm International Peace Research Institute (SIPRI) database and it tracks only what is calls "major weapons" (see section 3 in https://sipri.org/databases/armstransfers/sources-and-method...). So small guns or similar arms will not be covered. Also, I have not checked the dataset yet, but from the description, a chord diagram of source and destination nations could probably be plotted from the SIPRI database. Would make for a good spare-time dataviz project!

I believe this is more bombs and heavy weaponry than light arms.

Oh I see that now. Its not very obvious at first glance what is being illustrated.

That's why Belgium is so low on the list.
