Our World in Data has created 100s of heat maps with scroll bars for
adjusting the year. The maps as well as the underlying data is under an
open license.
Example include these
https://ourworldindata.org/obesity/
When one puts their cursor over the country in question they get the
underlying data and the country is highlighted. What would be required for
use to support this sort of technology within Wikipedia?
