Listen to more plots properties on selected and click events

[ShootingStarD]

Description

I just stumbled across the dash documentation regarding selection here. Here they have a very useful features which allows to also capture the custom_data , that is data that we add to the points plotted. It can be used so that the developer add index of rows in the custom_data (very easy with plotly express hover_data argument) and then the developer of the dash op can link the point selected with a row of its dataframe to apply further processing.

This is not the case in Taipy where you only capture the position lat lon or the x y coordinate of the plot for a click event, and the index of the traces selected for the selected property.

Would it be possible for taipy to have this dash feature ? i.e. listen to the same property as dash, or simply get access to the custom_data of points clicked/selected?

A use case for that is the one I describe here :
"Just to be clear, my end goal is to be able to click on a point on the map, and get the index of the element of dataframe corresponding to the point I clicked."

I am not part of the Taipy team so I cannot assign it to you, moreover since it supposes major changes in taipy callback return structures, it has to be first discussed with Taipy maintainers

@ShootingStarD I like this issue and how detailed it is. Thank you! We'll discuss it
