Create Radar Chart with Tableau Viz Extensions

What is a Radar Chart?

A radar chart is a multivariate data visualization that displays three or more variables on axes that all start from a central point. The result is a polygon whose shape makes patterns, strengths, and gaps easy to compare at a glance. It’s also known as a spider chart, web chart, or star chart.

A radar chart arranges each variable on its own radial axis; all evenly spaced around a circle. Data values are plotted along each axis and then connected to form a closed shape. This makes it ideal for showing profiles, comparisons, and patterns across multiple dimensions.
