Noob question about data for the new "Package Dependencies"

Just starting to prototype a few viz, and am obviously missing some fundamentals. :slight_smile:

I read the introduction to data, but don’t see something equivalent to the usage as per this new observable “Package Dependenices”

Since we are still using d3 v4, this is very helpful:

Thanks, Mike, the only thing I am missing now is s where you set the Url prefix to ‘’ in the code?

If you want this to visualize dependencies of a package that’s not on npm, I suspect you’ll need to edit the notebook and replace the calls to require.resolve with something else that points to your package.json.

Ah–got it! Thanks, Mike
