Data-driven styles
A renderer defines which symbols are applied to each feature. In the case of a data-driven visualization, the symbol is always determined based on a data (or attribute) value returned from a field in the data layer, or from a value returned from an Arcade expression.
- Field value (and optional normalization field) - Field values can determine the visual properties of the symbol. Visualizations created with field values can be persisted in web maps/scenes and exported to JSON.
- Arcade expression - An expression evaluating to a number or text value. This expression may be persisted and shared to items on ArcGIS Online or ArcGIS Enterprise portal. Visualizations created with Arcade expressions can be persisted in web maps/scenes and exported to JSON.

- 2. Provides an API for time-aware layers and time extent on layers and the geoview
