RaceNone

RaceNone is an option used in programming libraries, like Plotly, to specify that a particular trace or data series should be excluded from any animated race or transition. When creating animated visualizations, multiple data traces can be animated together, often with a "race" to show changes over time. Setting RaceNone means that specific series won't participate in these animations, allowing for static elements or overlays to remain unchanged, providing clarity or emphasizing certain data points without animation effects.
