Ancestral-Region Tree
The tree figure shows tip regions and internal ancestral region calls from the owned geographic-state reconstruction.
Geographic Map
The package includes the self-contained map artifact geographic-region-map.html.

Limitations
- some ancestral regions remain ambiguous and should be reviewed through the node probability ledger
- one or more discrete states are represented by fewer than two taxa and should be interpreted cautiously
- one or more states are represented by fewer than two taxa
- sparse-state transition estimates may be unstable for one or more source-target paths
