Can you build a recognizable World Map in under 500 bytes?

I know this doesn't meet the spirit of the challenge, but...

          _,--',   _._.--._____
   .--.--';_'-.', ";_      _.,-'
  .'--'.  _.'    {`'-;_ .-.>.'
        '-:_      )  / `' '=.
          ) >     {_/,     /~)
  snd     |/               `^ .'

U+1F5FA does it in 4 bytes!

I asked deepseek to turn this into an offscreen-canvas-based ascii renderer: https://retr0.id/stuff/worldgolf.html

Weighs in at 379 bytes (or 378 if you trim the newline). Obviously it is font-dependent, but it works on my machine!

Edit: golfed a bit further, but unsure how reliable it'll be with different fonts: https://retr0.id/stuff/worldgolf2.html

it said recognizable, and I recognize this :)

One could probably map this in JavaScript in 3D on a rotating sphere and it'd be a "recognizable world map" of sorts.

Why is there a lake in Africa near Congo/Gabon istead of one near Uganda?

Also, can this be done with png? Most consecutive lines are very similar, so I'd expect the algebraic pass to be very useful.

Africa and Europe are connected through Spain.

There's no Suez channel.

There are plenty of approximation: it's the whole point of the thing... You only get 1013 bytes (or, well, 500 bytes in the question asked).

If you were to render only one lake in Africa I would expect Lake Victoria

With a whooping 500 bytes it should have sound, animation and disco lights[1][2].

Its a fun challenge.

I used https://squoosh.app to make a pretty good one. Mostly just a resize and then OxiPNG for compression. Managed a 124x62 black/white image. OP has a resolution of 195x53, so I had very similar, but slightly worse i think? mostly a different aspect ratio + map projection i think.

playing with Squoosh.app is very fun, and you can very easily see how the jump from 500b to 1-2kb turns a map from "awful" to "very good" with the right settings.

great job, looks like you got it down to 786 bytes of html and under 400 for the map data. I like your approach.

The ASCII art reminds me of teletext.. this page shows a globe on a teletext page: https://www.wikiwand.com/en/Teletext

you could save some bytes by removing new Zealand, the world would still be recognizable ;)
