Reproducer:

Open Demo 3 and Demo 4

Observed behavior:

Selection highlight is missing in scatter plots and cannot select items in scatterplots.

Expected behavior:

Dots in scatterplot should be selectable and highlighted.
If a table row is selected the dot should be highlighted in the scatterplot.

@ngehlenborg : My guess is that for large datasets, we need not just the ability to link individual datapoints, but to drag a rect to select all the points in a region? That might be better handled as a distinct issue, but I want to clarify scope.

Can the existing scatterplot be removed? Can documentation refer to https://github.com/datavisyn/phovea_vis_scatterplot? How would a new user know that it exists, and is the best thing to use?

invalid: removed
