Hello @hellonearthis . I don’t know if I am exactly clear on what you’re asking. With regard to manipulating hierarchical data for use in charts, etc, does anything shared in [this thread](https://talk.observablehq.com/t/how-to-move-from-d3-group-to-a-format-that-works-for-a-sunburst-chart/3931) help you? Basically, the discussion relates to using d3 group, roll-up and hierarchy to get data into a format expected by a sunburst chart.
