Editing/Adding meta-data after some processing in Observable

In a visualization I am working on I would like Observable to read in the raw data, do the work to extract nodes, and then let the user manually order nodes and assign colors to parents and nodes. This info should be saved (with the data?)

Any thoughts?
Would you do this all in the visualization?
Are there other, table-based tools, you can suggest?

  • Thanks, Karl

The saving of the data would either be to the users localhost or the user would have to export the data (download as json) and then load it.


The rest of the desired actions seem doable but I have not seen it done on observable.

A good starting point would be: Interactive Tree Diagram (D3v3) / Aaron Kyle Dennis / Observable
