Graphics and Canvas

Graphics and Canvas

Graphics controls host custom drawing, OpenGL scenes, SVG imagery, and lightweight visualization surfaces.

Chart-specific controls belong to ChartKit. WidgetKit graphics controls are intended for non-chart rendering surfaces, previews, and custom painted UI.

Notes

• Keep drawing logic separate from layout code.
• Use stable canvas dimensions where possible.
• Validate high-DPI behavior.
• For SVG display, decide whether the original SVG color or runtime tint color should be used.
