//! Statistical Process Control (SPC) charts.
//!
//! Provides control chart implementations for both variables and attributes data.
//!
//! # Variables Charts
//!
//! - [`XBarRChart`] — X-bar and Range chart for subgroup data (n=2..=25)
//! - [`XBarSChart`] — X-bar and Standard Deviation chart for subgroup data (n=2..=25)
//! - [`IndividualMRChart`] — Individual and Moving Range chart for individual observations
//!
//! # Attributes Charts
//!
//! - [`PChart`] — Proportion nonconforming (variable sample size)
//! - [`NPChart`] — Count of nonconforming items (constant sample size)
//! - [`CChart`] — Count of defects per unit (constant area of opportunity)
//! - [`UChart`] — Defects per unit (variable area of opportunity)
//!
//! # Run Rules
//!
//! - [`RuleSet`] — any subset of the tests; [`RuleSet::shewhart`] (the 3-sigma
//!   test alone) is the default, [`RuleSet::named`] looks up a named set
//! - [`WesternElectricRules`] — the 4 classic run rules (eight points on one side)
//! - [`NelsonRules`] — Nelson's 8 rules (nine points on one side)
//!
