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 used dimensionality reduction to make it 2D

    Huh, interesting. So is the idea to spread the data out as much an possible, while keeping “similar” communities near each other? What was the dimensionality of the original set?
