A radial chart is a data visualization in which data values are encoded as positions, lengths, or areas along circular paths radiating from a central origin. Variables or categories are arranged angularly around the circle, with magnitude represented by radial distance, arc length, or sector area. Common variants include radial bar charts, radial histograms, and circular scatter plots. The form reveals cyclical patterns, enables magnitude comparison across angular sectors, and suits hierarchical or temporal data with inherent cycles. It is constructed by mapping data values to angular and radial coordinates in polar space. [formal: charta radialis | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A human-made data visualization form in which data values are encoded along circular paths or radii emanating from a central point, enabling display of cyclical patterns, hierarchical relationships, or multi-variable data in a circular layout.

A radial chart IS a specific kind of plot — it encodes data using angular and radial positions in polar coordinates rather than Cartesian ones. It belongs to the class of plots by sharing the fundamental property of mapping data values to visual spatial position.
