Morton Skulls
This map plots the geocoded skull groups from the PLOS Biology supplementary tables. Each dot uses the provided plotting coordinates, scales its size by cranial volume, and shifts color with volume so larger means stand out visually.
The mapped locations are approximate editorial placements for visualization only. They are not original specimen coordinates or exact recovery/provenance data from Morton's collection.

Notes
- Hover a dot to see the group name, source, location label, sample size, mean cranial volume, and location-confidence label.
- The plotted positions use the `plot_lat` and `plot_lon` fields from your CSV so overlapping points can be nudged apart without changing the underlying reference location.
- Historical labels in the dataset are preserved as source labels. They should not be read as modern biological categories.
