What dimensionality reduction algorithm is being used? PCA? UMAP? Of course better ones are likely to give better 2D representations. I've had this same idea to use the point cloud visualization to improve my own take on language model games - but I when I experimented with this, I found that even the best 2D representations were still quite bad in the context of trying to help out humans.
