SwiftUI Chart3D Developer

Quick Start

Use this skill for Swift Charts 3D visualization work. For windows, RealityView, Model3D, attachments, gestures outside charts, or immersive scene lifecycle, switch to $spatial-swiftui-developer.

1. Confirm the third dimension adds meaningful information; prefer 2D charts when depth does not improve interpretation.
2. Choose the chart form: 3D marks for sampled data or SurfacePlot for y = f(x, z) surfaces.
3. Bind Chart3DPose when the chart needs a stable initial view or interactive rotation state.
4. Set explicit x/y/z domains and labels so the plot volume remains readable.

Load References When

Reference	When to Use
charts-3d.md	When implementing Chart3D, SurfacePlot, 3D marks, scales, axes, pose, or camera projection.

Workflow

1. Define x, y, and z semantics before writing marks.
2. Choose marks, surface style, chart scales, and axis labels.
3. Add pose and projection only when they improve interpretation.
4. Keep chart state in SwiftUI and avoid mixing Chart3D with RealityKit scene ownership unless the surrounding view requires it.

Guardrails

• Do not use Chart3D for novelty; a 2D chart is often clearer.
• Do not leave unlabeled axes or implicit domains for production charts.
• Do not route general spatial UI layout questions here; use $spatial-swiftui-developer.

Output Expectations

Provide:

• why Chart3D is warranted
• which chart reference was used
• the marks, surface, scales, labels, and pose chosen
• the fallback to 2D or spatial SwiftUI routing if applicable
