I also attempted to simplify the map by aggregating booths located within a single suburb or locality.
Mapping the whole of Australia in this fashion was such a massively frustrating undertaking that I probably won't ever do it again. But maybe some metro area maps could be in the works if I can tear myself away from the dartboard for a while.
