What good is placement within a matrix if you can't see what the axes are?

I don't get it as well.

The color dimension is configurable, so it makes sense.

But I don't get what the 3 dimensions of spatial coordinates are, and how to change them.

--- Edit

Alright my bad it's actually explained in the "tour": https://pair-code.github.io/understanding-umap/

It seems to be some kind of multivariate PCA.

I actually prefer this style of visualization. I think the 3D visualization just adds needless complexity.

Or for 3 dimensional data I like bubble charts like this: https://mezziapp.com/dashboard/?id=8qFZ3RPiLKTCK3uk4gmG

I guess it's a Principle Component Analysis (PCA) dimensionality reduction so the axes are not necessarily concepts/features with names. More just "abstract dimensions of similarity."

I feel like this should somehow be combined with https://agar.io

Would be nice to be able to use custom metrics or scripts or indicators for the various axes/features and then show a movie of the display over time. Do the stocks that take off appear randomly or do they exhibit similar behavior?

I wish they had comments about what the clusters are and what the "empty loops" are

This looks pretty, but it has the rather serious limitation that you can't search for a company, and then see what its neighbors are.

Er, actually it is possible if you click one of the (unlabeled) neighbors, then zoom back in and hover around to find the original company again. But whether this works seems to depend on which color scheme is active.

In general, most interactions force you to zoom out and lose your place, and sometimes it just keeps rotating for no apparent reason.

NuScale Power (SMR) is categorized as "Life Sciences / Agricultural Production-crops", which makes me question the rest of the data.
