Bar Mark

Swift Charts calls visual elements "marks"

Code

// We add a tabBar
// then we build a `BarMark` with 2 elements

import Charts
import SwiftUI

struct ContentView: View {
    @State private var selection = 2
    
    var body: some View {
        TabView(selection: $selection) {
            WinesTab()
                .tabItem {
                    Label("Wines", systemImage: "chart.bar.doc.horizontal")
                }
                .tag(1)
        }
    }
}

struct WinesTab: View {
    var body: some View {
        Chart {
            BarMark (
                x: .value("Name", "Margaux"),
                y: .value("Sales", 900)
            )

            )
        }
