This was my first attempt at making a map using QGIS. In my oppinion, it went okay! Learning about the "Layout" feature made it a lot easier to create a nice image than I expected, even though I probably should have spent some more time on the text bits.
I'm still not sure about the color scale. Almost the entire map has colors that don't come very close to the 0 and 100% colors, but they do still exist. There might have been a better solution, but in the end I decided I liked this as it tells the story I wanted to just fine. It was made for #MapPromptMonday on Twitter/Mastodon.
