Description

I think at this point the data visualisation has become sort of a staple in the community and implementation-wise it is only an incremental change. We should add an option to render only one of the two sides of a violin. Horizontally, this allows for ridgeline plots.

Research direction

Start by locating the existing violin-plot implementation and its tests, then trace how the two sides are rendered and how horizontal orientation is handled. Define the option's behavior for rendering one side, including the ridgeline-plot use case, and add coverage showing that the selected side renders correctly.
