They're great for rapid wire-frame prototyping.
It’s dynamically rough so it’s different each time, but it’s not over done
I’m still hanging out for a browser implementation of Fiziko (https://news.ycombinator.com/item?id=21651240) though, which would be a whole other cool aesthetic.
The blog post [1] about fiziko describes how it calculates parallel bezier curves using line intersection and curves of varying thinkness. The code about the coastal lines also uses a similar technique and describes how to get the result step by step.

When combined with a handwritten font like humour sans[0] You can instantly turn a chart into something that looks more like an XKCD drawing.
No idea why, but I find the hand-drawn look is universally more engaging for charts and diagrams, causing people to actually pay attention and ask questions. It looks like some of the example links[1] need updating. But the WiredJS[2] site is a good demo of the look I am describing.
