For anyone wondering: these kind of plots are sometimes still called "joyplots", but more and more commonly referred to as "ridgeline plots". Many plotting libraries have support for them nowadays, some more 'native support' than others. For ggplot2 there's ggridges [0], the seaborn docs have an example here [1] or in my own ggplot2 inspired lib for Nim [2] it's built in:
Yup. At some point there was a storm in a teacup in the dataviz community about the name of the plot, because someone discovered the plot, discovered Joy Division, and learned of the origins of the name -- then immediately had to get offended and mount a crusade about it.
Luckily, "ridgeline" does describe the plot type quite well, maybe even better than "joyplot".
I wrote a thing for it to generate images based on SRTM data, for drawing "Joy Division T-shirt" logos of islands. It worked pretty well but I never got round to having the T-shirts printed.
Usually a heightmap is x,y grid (2d array) with values between 0 and 255 which represent a grey scale value. Sometimes these values could also be -1 to 1 or 0 to 1 or something similar.

This is incredibly uncharitable. Everyone has one or more communities they dislike - especially when they send a certain type of traffic your way - for jwz, HN is on his "no thanks" list. As for why, I can think of a few reasons why an old school hacker like jwz may dislike "Hacker News" and its values/ethos.
Check out his public complaint that "signal leaks his phone number" and moxie's patient, thorough explanations and what followed, including the re-editing the original post.
jwz is totally allowed to be as bigger ass as he likes with my blessing. So can rms. To eachother even. It's happened! Both are difficult to get on with. So what? So that's a factor in why you get a hairy testicle in an eggcup linking to jwz.org from this site. Hardly a big deal really and you're entitled to disagree and think the testicle and ranting is lovely. Not sure why you're taking offence about my pointing it out but you're entitled to for sure.
I don't like posting video links but this doco is worth watching if you're into Joy Division (this is a deeplink where Peter Saville explains where the famous cover came from):
Never thought about it like that, but i concur. (addendum) Thank you for the inspiration. Reminds me of Einstein: "When i could stand in a train that travels at the speed of light and look in a mirror, what do i see?"
I was kind of disappointed when no one noticed this (and the associated illustration) in our blog about Super Bowl LVII trends: "While the so-called NFL cities across the country are loyal to their local teams, looking at traffic trends across cities from both conferences makes it clear that fans everywhere find joy, not division, in the unknown pleasures of a good halftime show."
I have this album hanging on the wall in my living room. The inside sleeve has a comparably small illustration of a hand opening a door from the inside of the room.
When I was a young lad, my parents got me that book for Christmas. I loved it. When Unknown Pleasures came out I immediately recognized the image. I used to (I assume) bore people with my knowledge of its provenance - "You know, that image is ..."
I had cut it out of the book and pasted it on wall at some point. What I didn't find out until many years later was that Saville had use that book as the source, and not some earlier primary document.
Sadly can't provide a source but somewhere i heard that a woman who was involved with this picture or pulsars in general won a medal/prize for her scientific work. It was 1_000_000 € or £ can't RC. She donated all to science. Maybe that documenary video from sibling comment says something about it, an't watch since on the go.
Of course Peter Saville with Ben Kelly are living legends, but this article manages to mention none of them. They were the forefront of modern design. They are also featured in several movies.
Usually I'd agree, but I wouldn't call the Kottke post (The blog that just had it's 25th birthday: https://news.ycombinator.com/item?id=35163193) blog spam, even if just for the fact that it's more pleasant to read than the scientificamerican.com version with ads, cookie banners and newsletter signup modals.
