The example https://editor.p5js.org/p5/sketches/rJZlz4ly7_m gives this error message:
Font could not be loaded: https://rawgit.com/processing/p5.js-website/master/dist/assets/examples/assets/SourceSansPro-Regular.otf
Seems weird because
1) The link works
2) The actual link in the code is to the asset folder, which also contains a font
From what I can tell it seems there's something wrong with the font, can you try another one see if that works?
the issue here is that rawgit has been sunset鈥攖he examples need to be updated to use a service besides rawgit!
I forgot about this but yes I found this across a lot of the sketches under the p5 account, lots of the assets are all trying to pull from rawgit.
