Make demo of interactive plotting of data

Make a demonstration of interactive plotting of X-ray data. This should be lightweight and quick enough to use through a browser. Examples could be to use:

• Plotly (Python)
• Solara (Python)

Ideally this should work for any kind of data (2D/3D scatterplots/point-clouds) and also 3D/4D tomograms.

If data is too large, we can use a subset or downscale it.
