• Improved robustness of internal stat layers when handling unknown or missing input parts.
  • geom_colon() no longer errors when every input row references an unknown part; the layer now returns an empty polygon layer.
  • geom_colon_label() correctly honours a user-mapped label aesthetic (previously overwritten by the derived label).
  • Added a variant registry: register_colon_variant() and list_colon_variants() for user-defined colon layouts alongside the built-in "standard" and "sescd" variants.
  • Added a Basics vignette walking through the core plotting workflow.
  • Expanded the test suite to cover blueprint geometry, sf helpers, stat layers, and the variant registry.
  • Initial release.
  • geom_colon() and geom_colon_label() for visualizing the colon with ggplot2.
  • Blueprint system for configurable colon anatomical layouts, with "standard" and "sescd" variants shipped.
