A visual encoding is a systematic mapping from data dimensions to visual properties — such as position on a spatial axis, color hue or lightness, size (area, length, angle), shape, and texture — designed so that the resulting visual display permits perception of data relationships. It is built by human designers to extend cognitive capacity for pattern recognition beyond what raw data allows. The encoding persists through explicit conventions taught in statistics, information design, and data visualization; through shared visual vocabularies in scientific and commercial practice; and through standardized color maps and glyph systems. A valid encoding is perceptually discriminable, semantically interpretable, and consistent within a given display.

Definition
Why it is in scope
A visual encoding is a human-made mapping system that translates data attributes into visual properties such as position, color, size, and shape. It is a conceptual framework developed in information design and statistics to enable humans to perceive patterns, relationships, and anomalies in data through visual perception. The encoding is built through sustained practice in visualization design and persists through teaching, conventions, and standards in data representation.

Visual encoding IS a specific kind of data visualization: it maps data attributes to visual properties (position, color, size) to represent information. A competent speaker would call visual encoding a form of data visualization.

TESTED INSTANCE_OF: mosaic plot IS a specific kind of visual encoding — it encodes two categorical variables using position (along a baseline) and area (perpendicular to baseline). A mosaic plot is a concrete instantiation of the general visual encoding concept.

A partial dependence plot is a specific type of visual encoding used to interpret machine learning models. It visualizes the marginal effect of one or two features on the predicted outcome using a plotted relationship, where the x-axis shows feature values and the y-axis shows predicted response. It is a concrete kind of visual encoding.

An alluvial diagram is a specific type of visual encoding (a flow diagram) that shows the transfer of quantities between nodes, using flowing ribbons whose widths are proportional to the flow quantities. It is a concrete kind of visual encoding used in data visualization.
