Can anyone find some diagrams or charts on plentiful resources per continent or country?

Question

I thought this would be fairly easy to find, but I've been searching for a while and I'm not finding anything - I'm looking for a chart or diagram of some basic exports, globally. I'm writing an essay that really depends on finding this information :\

may help

https://www.cia.gov/library/publications/the-world-factbook/geos/bm.html
has maps of countries with natural resources in text nearby,
but not *on* the map.

Some natural resources may be so ubiquitous that they would be assumed. Take for instance, solar energy in the Sahara Desert. I expect this would not show up on most maps of natural resource.
