Is it possible to choose at which level the flows should be grouped/ungrouped in Sankey diagram? #172

Question 1: is it possible to choose at which level the flows should be grouped/ungrouped in Sankey diagram? For example, at depth of 2, there are two nodes for A11 (i.e.: ungrouped rather than having 1 node of A11, and two flows fed into it), but on the very right hand side, flows B, C, D shall be grouped (eg. node D has two inflows). Here A represents functional unit, A1, A11... represent activities.

Since I have very limited number of flows in the biosphere database, B, C, D actually represent the biosphere flows. So: Question 2: is it possible to show biosphere flows in the Sankey diagram?

I have calculated all the results needed to generate this visualization in Brightway, in the form of a nested dictionary. image

This is definitely possible, just not in the ActivityBrowser :smile: I suggest you have a look at https://ricklupton.github.io/d3-sankey-diagram/. If you already have your results in a dictionary, it should be rather simple to create a sankey diagram with the ipysankeywidget. You can directly create them in a jupyter notebook following the examples notebooks on the ipysankeywidget github page. This also allows you to add biosphere flows according to your requirements.
