Map consensus weight vs bandwidth for each bandwidth authority's votes

The new map on Relay Search is great! The consensus weight versus bandwidth map has been really helpful for analysing bandwidth authority behaviour. We now know that the measurements are biased towards the north of the northern hemisphere. (We don't know why yet: maybe the Internet is better, maybe the relays are all there, or maybe the bandwidth authorities are all there.)

I can look at the bias for the Guard and Exit flags by doing an aggregate search, then mapping it.

But I'd also like to see the bias for each bandwidth authority, using the bandwidth figures in their votes. Is this possible in Relay Search?

Having this map on a country level would help us when we start experimenting with moving the servers around, or pooling them, or using a CDN.
