Show HN: Prime Number Grid Visualizer

Hello HN. I made this simple little tool that let's you input rows and columns to create a grid, then it plots the grid with prime numbers.

I made it for fun, but I'd love suggestions on how I can improve it in any way. Thanks, love you.

So cool! I'd like to be able to start at any number

Thanks! Do you mean you’d like to be able to input any number you like?

The numbered values are editable inputs. You can click into them and type in the amount you’d like. If you couldn’t tell they were editable inputs, that’s valuable feedback! I’ll redesign them to make it more obvious that you can do so, and don’t have to just click the +/- buttons.
