If you like information about minerals, you might find my visualisation of world production of different minerals also interesting:<p><a href="https://ninhursag.herokuapp.com/" rel="nofollow">https://ninhursag.herokuapp.com/</a><p>The green line shows world production form year 1900 to about 2020, depending on data availability. Yellowish green line shows available reserves – that is ‘easily’ available or economically feasible resources.<p>Most of USGS data series 140 minerals are included, and you can try to fit various Scipy distribution functions with the data to see some estimates.<p>PS. It’s on a free tier so it takes a few seconds to boot, if no one have visited recently.
