Add Metadata to create a t-SNE/UMAP or other visualization

[VincentGardeux]

It would be cool to be able to create a new visualization from any metadata? For e.g., I have a public project, which already has a UMAP. I've re-created the analysis on ASAP (https://asap.epfl.ch/projects/8jaw4y) from the count table, and now, I want to be able to display both my UMAP, and the original UMAP (Metadata X and Y) from the metadata?
