struct ChartView: View {
    @State private var scale: CGFloat = 1.0
    
    var body: some View {
        VStack {
            Text("Chart View")
                .font(.title)
            
            GeometryReader { geometry in
                Chart()
                    .scaleEffect(self.scale)
                    .gesture(
                        MagnificationGesture()
                            .onChanged { value in
                                self.scale = value.magnitude
                            }
                    )
                    .frame(width: geometry.size.width, height: geometry.size.height * 0.8)
            }
        }
    }
