Swift Charts

This is a comprehensive reference for Swift Charts that covers everything from basic bar and line charts to advanced features like vectorized plots for large datasets and iOS 17+ scrollable charts. You'll want this when implementing any data visualization in SwiftUI, whether you're building a simple pie chart or something specialized like a heat map or Gantt chart. The workflow section walks you through the typical pattern of defining data, choosing mark types, and encoding visual channels, while the code samples show real implementations for stacked bars, range areas, and donut charts with inner radius ratios. It includes the kind of details you actually need, like how to layer multiple AxisMarks for different grid and label intervals, and covers selection binding for interactive charts. The review checklist at the end is handy for auditing existing chart code.
