This is my first try at creating a map of lemmy. I based it on the overlap of commentors that visited certain communities.

I only used communities that were on the top 35 active instances for the past month and limited the comments to go back to a maximum of August 1 2024 (sometimes shorter if I got an invalid response.)

I scaled it so it was based on percentage of comments made by a commentor in that community.

Here is the code for the crawler and data that was used to make the map:

I’m finding new communities I want to explore from this thing. Very neat!

Can anyone ELI5 what the axes mean?

Nothing. There were far more dimensions in the original data and the author asked the computer to squash that down into two axes in whatever way preserved groupings

One is labelled Y.

I’m assuming the other is X… but might be Z if they’re fun

I pretty much only browse /all , so I’m throwing the numbers off! I don’t know myself with which communities i interact most.

Yeah I’ve noticed there aren’t many clusters that encode specific ideas (there are a few like the anime, nsfw, or sometimes instance level clusters). Most of it just seems to be a blend. Sorta disappointing.

There’s not enough data yet for the noise to cancel itself out, I think.

Place and language-specific clusters are pretty coherent, if you go looking.

Are they clustered based on shared userbase?

Yeah pretty much. There is also a weighting based on the percentage of comments in that community that come from that user.

Most of the value comes from the labels which require the webGL though

I like how the vertical column just says y, and the horizontal says nothing at all!

that’s just poor cropping. The horizontal axis is labelled “x”
