I used 2 different metrics to rank the communities:
at first I sorted the communities by their total subscriber counts. The two diagrams coming from this sort are easily recognizable because hexbear has a big chunk of the communities in them.
the second one ranks them by active users per month. These are the ones where lemmy.world has >50%
For each of the 2 ranking metrics there are 2 different chars:
Labeled "By Community Count": just count the amount of communities out of the 100 biggest that are on a given server
Labeled "By Community Users": sum up the amount of users (active/month or total suscribers) in all of the 100 biggest that are on a given server
