Cool data, but your charts are absolutely horrible

1) Try to pick more different colors. Choosing two different shades of pink, of grey and of cyan to represent unrelated things makes zero sense.

2) The sellers-by-country map is completely unreadable, it's just very slight variations of the shades of pink. Italy looks almost as pink as Canada, but it's 16 times less active.

or just add labels on the graph itself and you won't even need colors (bonus for the color blinds)
