For example...

• Tweets containing hashtags e.g. #atcal, #music, #justinbieber, etc


Visualization Question

• What happens if tags co-occur, i.e. the sets are not disjoint?

• Heavy amount of research work done in creating area-proportional Euler diagrams


DataCreate

proportional areas

Image Label Image

Creating proportional areas only part of the problem for effective communication


Naive Solution

• consider set of 6 tweets
