//! Polygon-based plotting utilities.
//!
//! This module provides utilities for converting fitted diagram shapes into
//! polygons and decomposing them into exclusive regions for visualization.
//!
//! ## Features
//!
//! - Polygon clipping operations (intersection, union, difference, xor)
//! - Region decomposition for exclusive area visualization
//! - Label-anchor utilities (poles of inaccessibility, principal axis,
//!   inscribed rectangles)
//! - Label placement ([`place_labels`]) — every requested region gets a
//!   position back, interior when the label fits inside the polygon,
//!   exterior otherwise, with a `tether` so callers can draw a leader line
//!
//! This module is only available when the `plotting` feature is enabled.
