Swift Charts를 사용하여 데이터 시각화를 구현, 검토 또는 개선합니다. 막대, 선, 영역, 점, 파이, 도넛 또는 iOS 26 3D 차트를 만들 때; 차트 선택, 스크롤, 주석, 축, 스케일, 범례 또는 foregroundStyle 그룹화를 추가할 때; BarPlot, LinePlot, AreaPlot, PointPlot, Chart3D 또는 SurfacePlot으로 함수를 플로팅할 때; 또는 히트맵, 간트 차트, 그룹화된 막대, 스파크라인, 임계값 선 또는 공간 시각화를 생성할 때 사용하세요.
이 스킬은 Swift Charts 프레임워크를 활용하여 iOS/macOS/watchOS/tvOS 앱에서 데이터 시각화를 구현, 검토 또는 개선하는 데 특화되어 있습니다. Swift Charts는 Apple의 공식 그래프 라이브러리로, 막대(bar), 선(line), 영역(area), 점(point), 파이(pie), 도넛(donut) 차트는 물론 iOS 26에서 도입된 3D 차트와 표면 플롯(surface plot)을 포함한 다양한 차트 유형을 지원합니다. 이 스킬은 차트 선택, 스크롤, 주석, 축 커스터마이징, 스케일 조정, 범례 추가, foregroundStyle을 통한 데이터 그룹화 등 고급 기능을 다룰 수 있습니다. 또한 BarPlot, LinePlot, AreaPlot, PointPlot, Chart3D, SurfacePlot과 같은 플롯 유형을 사용하여 함수 기반 그래프를 그리거나, 히트맵, 간트 차트, 그룹화된 막대, 스파크라인, 임계값 선, 공간 시각화 등 복잡한 시각화를 생성할 수 있습니다. Xcode 및 SwiftUI와 완벽하게 통합되어 선언적 방식으로 데이터를 시각적으로 표현하며, Accessibility, 다크 모드, 다이나믹 타입 등 Apple의 생태계 기능을 자동으로 지원합니다.
