I’m trying to create a chart of counts of categories. It’s very simple and, though an Observable newbie, I’ve done this before several times. But I can’t do it this time.
I don’t understand why the histogram only shows the total of all data items rather than breaking it out into categories.
I have several other working instances of this. I can reproduce this particular erroneous behavior in a working instance by misspelling the column to be grouped. But that doesn’t seem to be the case here.
