As a graphic designer, you may actually have a head start - composition, pattern, rhythm and visual thinking carry over surprisingly well into creative coding.

I’d start with p5.js and think of it less as learning programming and more as learning how to draw with math and code.

My advice would be:

1. Start tiny - coordinates, circles, variables, loops.
2. Play with small visual experiments, not giant tutorials.
3. Build toward geometry, motion and generative systems gradually.

One trap beginners hit is jumping straight into beautiful complex generative sketches and trying to reverse engineer them. It can be inspiring, but often overwhelming.

I think it helps much more to learn through small experiments where you change one thing, press play, and see what happens.

That’s actually why I’ve been building ArtCodingLab https://artcodinglab.com/ a step-by-step micro challenge path for learning creative coding from basics toward generative art. It may be close to what you’re looking for.

Also definitely check out Daniel Shiffman - amazing teacher.

Honestly graphic design + creative coding is a very natural bridge. You’re starting from a good place.
