A radar chart, also known as "spider chart" or "web chart", displays multivariate data as a two-dimensional chart in which multiple axes are arranged in a circle and radiate from the same central point. Each data point is plotted on its corresponding axis, and the points are connected to form a polygon. Radar charts provide a quick and intuitive way to compare values across different variables, making it easy to identify strengths and weaknesses at a glance.

Radar charts are automatically supported by Ranking questions. To display a radar chart by default for a specific question, access its visualizer using the VisualizationPanel's getVisualizer(questionName) method and set the chartType property to "radar":

vizPanel.getVisualizer("smartphone-features").chartType = "radar";
