There's a github icon in the modal that pops up when you first use it. You can click the (?) button to see it again. Or here's the direct link https://github.com/eoin-barr/pathfinding-visualizer

(I'm not the author/OP but the code is pretty readable and it was really easy to get running with just `yarn; yarn dev`)

Just added a Github link to the navbar. If you have any ideas or see some here that you like that haven't been implemented go for it !
