Visualisation enhancements follow-up

[bgruening]

This issue is a follow-up to #20097 and I think we can crowd-source this a bit for new contributors.

No example data

• Cytoscape no example data
• FITS Graph Displays FITS Tables
• H5web
• Image Annotate Display and Annotate Images
• OpenLayers (similar data like Kepler?)
• Tiff Viewer
• Venn Diagram
• Vitessce
• Vizarr Viewer
• RNA Structure Viewer

Missing help

• aequatus
• ChiRAViz
• CSG Viewer <-- hide/remove, this is replaced by VTK
• Graph Visualization <--- hide/removed? We have Cyctoscape now and that one was based on Cytoscape?
• PCA 3D plot
• RNA Structure Viewer

Some general issues

• export button inside the text-editor should block if one export is running, otherwise multiple exports can be triggered simulanously
• image annotate needs an export button
• Kepler is displaying CSVs which is most of the times wrong
• The dataset selector is not displaying the HDA ID?
• for Vizarr / Vitessce it would be nice to test external data - they can in theory work with URLs and deferred data
• Trackster should be hidden?
• MSA is showing way too many different datatypes in the data select

General feature requests

• copy link feature like in tools to point someone to a Vis
• It would be nice if we can add custom "maps" to either Openlayers or Kepler. With custom maps we could display geojson of annotations, e.g. Tumors on a kidney or liver. We have tools that create such geojsons.

This great. Thank you. We should also add specific datatypes:

• cytoscapejson for cytoscape
• geocsv for kepler
