Show HN: MLGarden, a tool/toy to build and train simple neural networks visually (github.com)

I made this tool to get some better intuition on how neural networks/backpropagation worked, but I'm really unsure what to do with it now, so I've put it up on github, and I wrote a little primer on backprop and neural networks to showcase it.

Really curious to hear any thoughts you might have, or anything I got wrong in the write up!
