How to create bar chart with two or more bars per time period

Environment: Xcode 14.1 beta 3 on macOS Ventura Beta 9.

No longer need this, I found example of this.

struct LocationsChart: View {
    var body: some View {
        Chart {
            ForEach(seriesData, id: \.city) { series in
                ForEach(series.data, id: \.weekday) {
                    BarMark(
                        x: .value("Weekday", $0.weekday, unit: .day),
                        y: .value("Sales", $0.sales)
                    )
                }
                .foregroundStyle(by: .value("City", series.city))
                .position(by: .value("City", series.city))
            }
        }
    }
    let seriesData = [
        (
            city: "Cupertino", data: [
                (weekday: date(year: 2022, month: 5, day: 2), sales: 54),
                (weekday: date(year: 2022, month: 5, day: 3), sales: 42),
                (weekday: date(year: 2022, month: 5, day: 4), sales: 88),
                (weekday: date(year: 2022, month: 5, day: 5), sales: 49),
                (weekday: date(year: 2022, month: 5, day: 6), sales: 42),
                (weekday: date(year: 2022, month: 5, day: 7), sales: 125),
                (weekday: date(year: 2022, month: 5, day: 8), sales: 67)
            ]
        ),
        (
            city: "San Francisco", data: [
                (weekday: date(year: 2022, month: 5, day: 2), sales: 81),
                (weekday: date(year: 2022, month: 5, day: 3), sales: 90),
                (weekday: date(year: 2022, month: 5, day: 4), sales: 52),
                (weekday: date(year: 2022, month: 5, day: 5), sales: 72),
                (weekday: date(year: 2022, month: 5, day: 6), sales: 84),
                (weekday: date(year: 2022, month: 5, day: 7), sales: 84),
                (weekday: date(year: 2022, month: 5, day: 8), sales: 137)
            ]
        )
    ]
}

func date(year: Int, month: Int, day: Int = 1) -> Date {
    Calendar.current.date(from: DateComponents(year: year, month: month, day: day)) ?? Date()
}
