Data

Every layer may have some data associated with it. The "data" refers to a table of data where each row contains an observation and each column represents a variable that describes some property of each observation.

Data in this format is sometimes referred to as tidy data, flat data, primary data, atomic data, and unit record data.

You can pass tidy data to Lets-Plot in form of a Kotlin Map.

Basic Building Blocks

Points: points, jittered points

Lines: line, path, diagonal line, horizontal line, vertical line, segment, curve, spoke, step-function
