The Ganges–Brahmaputra basin. Have another version that includes even more rivers but that's taking forever.

The Amazon basin. Been wanting to do this for a while and finally managed to fix the errors I was getting.

I rather like how it turned out.

Did this last week but never shared: a profile of Hunter Mountain's ski pistes. Should I do more? This was just a test of an idea. Might choose a mountain in Europe or Japan next time.

Freshwater ecoregions of South America.

But why didn't you do this in #rayshader?! Of course I did, but am still sorting out a few issues because rivers don't fall neatly into categories...

Nine volcanoes of Japan. Mt. Fuji is instantly recognisable. The others too, I hope.

This took a while to get right. Looks like fancy chocolates, no? Or little LED buttons.

Back to ski runs. I liked @infowetrust.com's suggestion and got to work but was frustrated by label size and placement.

So I made it interactive, two ways. Which do you prefer?
