Teaswarm on a map! Tiles by Stamen Design. This is a variation of Teaswarm and Song Tea and Ceramics Map. Adding a bit of Beeswarm force layout jitter to reveal otherwise hidden points. Setting the collision higher and removing overlap entirely throws off the lat/long information too much. Circles are sized according to the number of teas taken from each location. Location data is imperfect. Specificity was preserved where possible. For example, some teas are just reported as being from Guangdong, while others are from a more specific place, like Chaozhou, Guangdong.
