I've created tools and dashboards for various interests of mine. These can be downloaded, copied and adapted to your use.
The dashboards and tools that I have shared here consist of a HTML file that reads a CSV or JSON stored in GitHub, and the data is drawn in the browser. Where you can input your own data (like the music/Spotify dashboard), the data is stored in your own browser.
The diaries refresh themselves from the services' data through scheduled GitHub Actions; the rest are built or updated by hand. The three diaries also come as drop-in viewers: open one, drop your own export (e.g. Spotify) on it, and you get the same dashboard for your data.
There's a folder for each viz in GitHub, with a README on how the data is refreshed. You can take any of them and you (or your AI agent) can rebuild it around your data. Many of the Tableau vizzes were made for #MakeoverMonday, the weekly challenge where the community remakes the same chart from the same data. The shared look is written up in STYLE.md; the chips below filter by theme, by kind, and by where a piece was made.
