It is not clear what benefit one gains by using specific Cartesian Chart wrappers such as the AreaChart or the LineChart, when instead all charts can be achieved using the ComposedChart.

Proposal:

• Deprecate LineChart, AreaChart, BarChart, ScatterChart
• Rename ComposedChart to CartesianChart

Advantages:

• Reduced API, thus user-facing complexity
• Reduced bug surface

Disadvantages:

• ?

Open Questions:

• The ScatterChart currently has a separate Tooltip behaviour - should the Scatterplot remain?
• Is the interface of the ComposedChart equal to the union of fields of the LineChart, BarChart and AreaChart? What is missing?
