More Metadata Plot Options

[manthey]

The metadata plot panel plots any discoverable plottable data. It would be nice to have some additional features:

• Optionally show image thumbnails in the hover box (also make annotation thumbnails optional?)
• Options to change the color scale
• Test with large annotations (both front and backend)
• Reconstruct folder/item level annotation bounding box to annotation id correspondence
• Improve documentation
• More tests
• Colors on the plot reflected on annotations
• TSNE/umap clustering of selected data
• Multiples of multiple violin plots
• Some method to open another image when a graph point comes from that adjacent image
• Pan and zoom to the bounding box of the current graph point. Possibly related to the previous item.
• Show a graph point based on the annotation under the cursor on the image
• Read adjacent dataframe files within an item / folder
• Presets
