This is very cool, but unfortunately it's hard to get a sense of what the actual spatial distribution of people looks like when nearby nodes are grouped into larger dots that obscure the local structure.
That is largely an artifact of the source data, sadly. I place the dots where they were found, if the dataset has that information, otherwise I georef them back to the "findsite" in the data, which aggregates many finds at one place. A lot of these were found in the 1800s and just dont have good find lla data.
