OptionalauthoringAn object containing metadata about the authoring process for creating a renderer object. This allows the authoring clients to save specific overridable settings so that next time it is accessed via the UI, their selections are remembered. Non-authoring clients should ignore it.
OptionaldescriptionThe text string that does not appear in the table of contents but may appear in the legend.

OptionalrotationString value (either geographic or arithmetic) which controls the origin and direction of rotation on point features. If the rotationType is defined as 'arithmetic', the symbol is rotated from East in a counter-clockwise direction where East is the 0� axis. If the rotationType is defined as 'geographic', the symbol is rotated from North in a clockwise direction where North is the 0� axis.
An object that represents how all features will be drawn.
The type of renderer. See RendererJsonType.
OptionalvisualAn array of visualVariable objects used for continuous color or size, simple, and unique values with feature opacity.
