I am trying to edit my tilemill legend so that instead of displaying a red rectangle as below, it displays a red circle (I'm making a proportional symbol map).
What line would I need to add in my legend code (see below) to make this happen?
On the mapbox website it says : "The advantage with html/css is that you can quickly make edits to the legend directly in TileMill, and maintain the ability to manipulate the legend styling with css even after the map has been exported to MBTile format. However, you are limited to right angles and solid colors, and may have to write many lines of code to create a relatively simple design." https://www.mapbox.com/tilemill/docs/guides/advanced-legends/
Hopefully "limited to right angles" does not mean that I cannot create a circle?
