What tool were those tree structure Illustrations created with? They look really nice!

Thanks! I used draw.io and tweaked a number of the display properties to make it look more like Excalidraw.

I love the styling of this blog post generally too - simple, attractive and pleasant to read - kudos

Did you do them by hand or use some algorithmic way to construct them?

Not the author, but looks similar to excalidraw.

this looks like draw.io with a custom font. edit: nope, i'm wrong, its excalidraw but the effect is almost identical in draw.io.
