Your document is clear, I do love "interactive infographics" to learn about things, and I really liked how you shared your doubts too (as a fellow solo dev, I relate :D)
Another ref you could check if you don't know them already: Nicky Case's "Shtuff" https://ncase.me/ especially the https://explorabl.es/ they made some time ago. While they do provide lots of texts, they rely on simple interactions and are very effective. I also very much enjoyed their Fireflies simulation: https://ncase.me/fireflies/
