I follow exactly 100 twitterers (and frankly, I have no idea how I could deal with more). So I thought it would be nice to see how they follow each other.
Once the edge list was done, it was easy to create some visualisations using my tool — I wrote about them on the product site: http://condensr.de/2020/12/05/another-large-map-example/ .
I thought that I might see at least two major clusters: the elearning people and the personal knowledge management/ visualisation people. But it turned out that they are so much interconnected that most layouts show just one large hair ball.

So I have to admit: it’s a bubble.
By the way, I color-coded two of the maps by gender. I wonder if 62 males and 34 females is too biased?
