Data Grouping

The group parameter is not a true aesthetic but controls how data is grouped for visualization:

Default Grouping Behavior:

Lets-Plot automatically groups data by discrete variables mapped to aesthetics like color, shape, linetype, etc. This creates separate visual elements (lines, paths, polygons) for each unique combination of these variables.

Explicit Group Control:

• Use group = "variableName" to group only by that specific variable, overriding default grouping

• Use group = listOf("var1", "var2", ...) to group by the interaction of multiple variables

• Use group = emptyList<Any>() to disable all the grouping completely
