Interactions from graph to datasource

Hello,
I want to build an application and i would like to know if bokeh is well suited for this and how to do it.

Use case is :

  • various objects (adresses, roads, trajectories…) are displayed on a map (~10 000 to 100 000 objects)
  • The user is able to interact with the map and create new objects or modify existing objetcs:
    • After with a right click on the map (new object) or existing object, a pop up appears
    • the pop up contains
      • fields that can be filled/modified by the user.
      • button to save the changes, that will affect the datasource
      • the content of the pop up depends on object type
  • Another button (outside the map) can trigger a calculation, using the updated datasource as argument :
    • the calculation is a python programm (it is complex and i dont want to learn JS for that)
    • the calculation can be long (1 second to 1 minutes)
    • when it is completed, it returns a new dataset to be shown on the map
  • Another button (outside the map) will save the data

I dont know how to create the interactions from the map to the datasource
how would you implement it ?
also, is the number of objects (up to 100 000) an issue ?

Thanks for your help

All of the interactions sound generally reasonable for a Bokeh server application, from a high level

You’ll have to describe your requirements in much more detail to expect concrete guidance.

This is not enough information to say. A 100k scatter plot is reasonable. A 100k node graph, with 10M edges, is not
