We should revisit the queries we're using to construct these charting responses to:

  2. Only group projects by categories that are included in the category query param list (less crucial, but would prevent the unexpected forest bar showing up in the case above)

It turns out this was a small bug in a function used to filter projects. this should be fixed now
