I clicked expecting some catalog of data structures but it was a pleasant surprise.

Includes Martin Fowler's strangler fig. Yes it is a design pattern and a tree.

It would be interesting to see the list of past trees. The most famous I can think of Donar's Oak (also called Thor's Oak), which was revered by Germanic pagans, and felled by Saint Boniface.

Of course: https://m.xkcd.com/2977/

Slightly off topic but does anyone know where to get a huge dataset of tree images? I'm talking millions.

There are surely more trees than this

And here I was excited to see disjoint subtrees of Wikipedia's articles.

Interesting to me how many of the European examples are yews and oaks.

Why is Pippi Longstocking's "soda pop tree" not on the list? It's dying and the whole of Sweden are freaking out. We're putting tax payer money on solving its disease. We're developing a vaccine to try and save it for gods sake. Yes, this is a very LOL type of situation to the rest of the world, I know that. But it's not a laughing matter in Sweden: https://www.slu.se/nyheter/2025/11/pippis-sockerdrickstrad-r...

I was unreasonably excited they included Pando.
