Hi Victor! This is such a great project. I posted a comment elsewhere about why I like it so much.
Will you be releasing more info about your research methods and pedagogical theory? Really interested to know more about how you make the sausage.
Also, wrt to Africa specifically, I do remember when I was doing history grad school about 10 years ago that one of the more provocative hypotheses at the time was that some or all tribes may be colonial constructs. Curious if you've engaged with that hypothesis, and more generally how you're going about mapping territories in Africa.
Great work, and I hope that you persevere and not let the haters get to you.
P.S.: Are you looking for any volunteers? I do full-stack web dev and have experience w/ Mapbox.
