    .AddItem("West", 94, Color.Green));

Create a Breakdown Chart

AnsiConsole.Write(new BreakdownChart()
    .AddItem("C#", 65, Color.Green)
    .AddItem("TypeScript", 25, Color.Blue)
    .AddItem("Python", 10, Color.Yellow));

Show a Calendar

To highlight dates, use Calendar.

var calendar = new Calendar(2025, 1)
    .AddCalendarEvent(2025, 1, 15)
    .AddCalendarEvent(2025, 1, 20)
    .HighlightStyle(Style.Parse("yellow bold"));
  
AnsiConsole.Write(calendar);
