[SDF Viewer] Add size guide to scatter plot #1265
Description
Similar to the colourbar provided for the colour series, it would be nice to show a scale for the size of points. Similar to this example from the internet.
In plotly this isn't available by default. There is this forum post about it. https://community.plotly.com/t/how-to-add-a-size-bar-to-a-scatter-plot/50167
