Any help // insight is appreciated!

It reminds me a bit of this error I ran into when importing another d3 tree notebook a few months ago, though that one seems to have been resolved (partially?). It’s a little puzzling because the PR to the runtime that Mike linked doesn’t seem to have been merged…
