How to change the dataset used by a chart using the "viewof" command

Hello, I am new to Observable and would like to ask help with the following:

I want to use the Hierarchical Edge Bundling chart to show the relations between sectors of an economy. I already arranged the data to show all relations (see

As the chart is too crowded, I would like to add the “viewof” command to allow for interactivity, only retaining flows in the economy that are more than 1 million, 10 million, or 100 million. I added the “viewof” command to show these categories, but I have not managed to understand how do you include the interactivity in this case. How do you link the chart and the various datasets to the viewof. Any suggestions?

A very artesan way would be to have a different graph for each different datasets. Yet if there is a way to include four versions of the same dataset and have the viewof comand change the data to be used, that would be great!

Thanks in advance!
