Configures the loading indicator.
When the widget visualizes local data, loading is instant. But when the widget is bound to a remote data source, loading may takes a considerable amount of time. To keep the viewer's attention, the widget can display a loading indicator.
To activate the loading indicator, assign true to the loadingIndicator.show option. Once data is loaded, the loading indicator will be hidden automatically.

This option supports the following colors:
- Hexadecimal colors
- RGB colors
- RGBA colors
