Write a program that lets users design charts
such as the following:

golden gate
brooklyn
delaware memorial
Mackinac

Use appropriate components to ask for the length, label, and color, then apply them when the user clicks an “Add Item” button. Allow the user to switch between bar charts and pie charts.
