Connector geometry for computed layout movement — connector_geometry • explodemap

Builds one line per moved group or feature, from the original anchor to the final anchor.

Usage

connector_geometry(
  layout,
  level = c("group", "feature"),
  id_col = NULL,
  threshold_m = 1,
  include_unmoved = FALSE,
  require_stable_id = identical(level, "feature")
)

Arguments

layout: A grouped_exploded_map.
level: Either "group" or "feature".
id_col: Optional feature ID column for level = "feature".
threshold_m: Minimum movement distance to mark a connector visible.
include_unmoved: Include zero-distance rows.
require_stable_id: Require a real feature ID column for feature-level persistent handoffs. When TRUE, row-number fallback IDs are rejected.

Value

An sf line layer with movement attributes.
