Fantastic app! (But I'm keeping my short wave radio anyway). Can't help but notice vast areas of radio deserts. I presume there are at least radio broadcasts there, but they don't stream?

What is the meaning of the size of the dots? I was guessing it's related to transmit power?

I think it represents the number of radio stations available for that city (each dot is a city, and you can switch individual radio stations using the list at the lower right corner of the screen)

It's most likely missing data in the radio directory they are using - I know of 5+ streaming channels in 2 African countries, yet both countries are totally blank.
