Following on from work done in #94, there are still some unresolved points, including:
Improving aesthetics of F1 origin area and all arrows
Figure need labels for Norris/Clarkson
Figure labels for the three Cameroon sites (?)
There area arrows on both ends of the spreading outbreaks other than F1. This is ambiguous as it could mean we infer movement in both directions, or it could mean we aren't sure. Better way to represent uncertainty?
