Test your geography knowledge of za warudo.
Dio Geo is a Scala.js and Slinky geography quiz app. It uses React's SVG support for the map.
You can try the app out here.
Also please note that I didn't choose the borders for the map or decide what is and is not a country. I'm just using Simple SVG World Map. There's an issue for adding more maps or locale support if you're interested.
I mainly created this to evaluate Slinky, but if you'd like to contribute regardless feel free to. I may or may not get to it myself eventually.
