Module chart 

Chart rendering algorithms for Presentar.

This module provides mathematical algorithms for chart rendering:

• Interpolation (linear, cubic spline, Catmull-Rom, Bezier)
• Path tessellation for GPU rendering
• Histogram binning
• Arc geometry computation
• Data normalization and scaling

Example

use presentar_core::chart::{Interpolator, CubicSpline, Point2D};

// Create a spline from control points
let points = vec![
    Point2D::new(0.0, 0.0),
    Point2D::new(1.0, 2.0),
    Point2D::new(2.0, 1.5),
    Point2D::new(3.0, 3.0),
];
let spline = CubicSpline::from_points(&points);

// Interpolate at any x value
let y = spline.interpolate(1.5);
