The tooltip context provider allows registering and retrieving tooltip content providers. When
a tooltip content provider is registered with a provider ID, then it must be retrieved with that
same provider ID. This allows a chart to have multiple tooltip content providers, depending on
the context or types of objects being moused over. When a tooltip content provider is registered
without a provider ID, then the default provider ID is used.
