In eulerr: Area-Proportional Euler and Venn Diagrams with Ellipses

Run eunoia label placement, expanding limits so exterior labels are not clipped. Drives one initial pass plus one re-measure pass when the limits widened by more than re_measure_threshold on the short side. Updates centers (and the complement slot on container_data) in place with placed ⁠(x, y)⁠ plus kind, tether_x, tether_y, leader_end_x, leader_end_y.

Description

When placement_opts is NULL, defaults to eunoia's raycast + POI tether.

Usage

apply_label_placement(
  centers,
  container_data,
  shapes,
  labels,
  quantities,
  annotations = NULL,
  placement_opts = NULL,
  do_complement_label = FALSE,
  limits,
  n_vertices,
  label_precision,
  re_measure_threshold = 0.01
)

Details

Returns a list with centers, container_data, and limits.
