Hi Connor, This is some nice visualisation! it is quite clear to see each data point. however, I don’t think this is readable since the size of each data point is quite abstract. It would be a lot more easier to read the graph with some scale some what each size represents. for example how you have a ratio to real size in a map. finally, the colour scheme for me is nice and clear, it really pops out because of the dark background. however, these colours aren’t colour blind friendly. It would be better to have a more accessible colour pallet.
