Oh, I’d LOVE to have a map like that! I remember seeing the Heezen-Tharp (at least, the Atlantic ocean floor part) in a schoolbook – and I think I didn’t listen to what the teacher said in that lessen because I was staring at the map all the time. A few years ago, I tried to generate a map like this...

No, that image was composed in Geocart out two instances of the “generalized Wagner” and one of the azimuthal equal-area projection. But it should be able to do that in d3, as well.

While nice to have, it's debatable whether or not this property is essential. Hmmm. To me, this simply doesn’t work, not even in a artistic application. Because it feels like two unrelated maps – there is “no flow” (don’t know if it’s clear what I’m meaning here). (Note: That is not the original as...

Looks like it may require a local JSON server? Ah yes. I always forget to mention that because I’ve got a local web server set up anyway so I run those scripts there. The easiest way to use one is probably something like XAMPP but as far as I remember you can also solve this problem by disabling a ...

Could be useful because SVG files are easier to edit losslessly than raster image files, if you know a bit about how they work. Yes, that’s why I included the button, I use it very often myself. It’s a bit of a nuisance sometimes that the full graticule is a single vector object – but of course tha...

The links to the files in Tobias's original email no longer work. Yes, I obviously removed them from the server at some point. I can’t find the starter kit that I sent you in 2020, but here’s a version from 2021, that I built for somebody else: https://map-projections.net/download/d3-starterkit.zip...

Of course it’s okay with me.

Yes, but I decided that I don’t want an optimal central meridian that needs more than 2 decimal places, so 11.55°E is still my favourite.

This assertion (…) is exceedingly odd to me. Well, I guess that’s just a devotee who doesn’t want to accept that his idol merely re-invented the wheel, not seeing that he could have spared a lot of work. And, by the way, probably declaring all Peters projection maps that are available today as not ...

May I present Milo's masterpiece of map-making, the crowning achievement of cartography, the pinnacle of projection! I do understand your bitterness here, but now you’re being unfair. Milo never said that the equirectangular projection is a masterpiece , nor claimed that it is "his", nor ...
