Overview
Principle of providing reusable drawing primitive functions (legends, stacked bars) that abstract common matplotlib operations for consistent visualization construction.
Description
Drawing primitives encapsulate frequently used matplotlib operations into composable functions. Manual legends allow adding custom color-coded legends to any axes. Stacked bar charts handle the coordinate arithmetic of stacking bar segments. These primitives ensure visual consistency across all Yellowbrick visualizers and reduce code duplication.
Usage
Use this principle when building custom visualizations that need manual legend construction, stacked bar charts, or other reusable rendering components.
Theoretical Basis
Composition over Inheritance: Drawing primitives are standalone functions that operate on any matplotlib Axes, rather than methods on a base class. This enables use in both Yellowbrick visualizers and custom user code.
