A spider chart (also called a radar chart or web chart) is a data visualization that displays multivariate data on a two-dimensional chart with three or more quantitative variables represented on axes radiating from a common origin. Each variable gets its own axis, evenly angularly spaced, and data values are plotted along each axis and connected to form a polygon. The parameters are: (1) the number of variables (axes), (2) the scale range per axis, and (3) the data points mapped onto the polygon vertices. It persists through software libraries and charting tools that render the geometric layout from structured tabular data.

Definition
Why it is in scope
A human-made data visualization technique that represents multivariate data on a two-dimensional chart with three or more variables starting from a common origin along axes arranged radially, built to persist through performance analysis and comparative reporting.

A spider chart (spider diagram, web chart) IS a specific kind of radar chart. Both use axes radiating from a common origin with values plotted as distance; spider charts fill the area between data points creating a web-like shape. The distinction is cosmetic — the underlying visualization structure is identical. A competent speaker would call a spider chart 'a radar chart'.
