I like how Web Development and User Experience grouping is way outside the central bubble.

Nonetheless, great visualization of a lot of data. I need to learn more about this:

UMAP: https://umap-learn.readthedocs.io/en/latest/

Nomic-Embed: https://www.nomic.ai/blog/posts/nomic-embed-text-v1

The visual groupings aren't perfect. For example, there are a quite a few COVID-19 tagged articles before 2020.
