Leaf

In botany, this refers to the flat, thin plant organ specialized for photosynthesis; in data visualization, particularly in a "tree" structure, it represents an endpoint or a data point that does not branch out further.

Stem

In data visualization, the ‘stem’ refers to a part of a stem-and-leaf plot, which represents the leading digits of the data points, while the leaves represent the final digits.
