Do you need WebGL to use Mapbox GL?

If you’re interested in creating an application that uses U.S. county data, you can download a Shapefile from census.gov’s data portal and upload it to Mapbox Studio’s Tilesets page. Mapbox GL requires WebGL support. Please check that you are using a supported browser and that WebGL is enabled. // Add a custom vector tileset source.
