Here's a map:
What does it show? It uses a rainbow colour palette that doesn't quite cover the basemap. It has a load of dot symbols of varying, equally bright colours. Some of the dots have a halo symbol behind them. Some of these halos exist without other overlying dots. Did someone spill a packet of Skittles on the map? Should it be titled 'a rainbow of fruit flavours'?
I have no idea what this map shows (sorry!). Answers on a postcard?
