I've just done the largest update to the #dataviz starter pack, with 30 accounts (20%) replaced. It means it will generate more content now. Might be worth re-clicking. Sadly, gender imbalance got worse. I saved 5 spots for women-run accounts. Send suggestions, including yourself! Replies or DMs.

I 3D-printed a Cheysson-style map of France showing the modal number of salutatory cheek-kisses in each department. It took ages. 3dartmaps.etsy.com/listing/4490...
A 3D-printed map that combines Émile Cheysson's fonts, patterns and coastal hatching with muted colours to display a modern dataset: the number of times the French kiss each other on the cheek when greeting in different parts of the country. The colour or pattern on the surface of each department shows the number of kisses employed by a plurality of its residents—from one to four—and the height reflects the percentage of that plurality. This one is made in blushing pink.
