I’ve been on a journey learning Haskell, and what better way to practice than by starting a little project of my own? Since I’m particularly interested in maps, I thought it would be nice to develop a map renderer using Haskell’s wonderful diagrams library.

The project is nowhere near finished—and probably never will be—but I still wanted to share it to see what others think and to get some feedback. It basically decodes vector tiles, interprets style specs (e.g., from MapTiler), and renders a single tile while applying the style (at least partially).

The development experience has been really nice, and it has introduced me to tons of concepts like lenses, parser combinators, GADTs, and more.

Cool! Any screenshots you could share?

Sure! Here’s an example of MapTiler’s [Dataviz](https://www.maptiler.com/maps/#style=dataviz&lang=auto&mode=2d&position=14.73/45.43656/12.32292) style
