ChartView
ChartView is a SwiftUI-native charting library that provides bar, line, pie, and ring chart components within a unified grid-based layout system. The library renders charts by composing SwiftUI views declaratively from data models, letting the framework handle layout and updates without intermediate drawing layers.
The library supports multiple chart types that share a common grid layout, enabling composable data visualizations with synchronized axes and backgrounds. Bar charts display data as vertical bars, line charts plot connected data points with gradient fills and optional markers, pie charts show proportional data as circular segments, and rings charts display concentric ring segments for multi-series comparison. Mixed chart types can combine multiple chart types within a single grid layout.
Chart configuration includes axis label placement at user-specified positions and configurable horizontal and vertical grid lines layered behind chart content for readability. The library builds chart views by mapping data arrays directly to SwiftUI view hierarchies, with geometric calculations for bar positioning, line paths, pie slice angles, and concentric ring arcs.
