A radar chart (also known as a spider chart, star chart, or polar chart) is a graphical method of displaying multivariate data in the form of a two-dimensional chart. Each variable is represented on its own axis that starts from the center of the chart, and all axes are arranged radially around the center point.

• Performance analysis and employee evaluations
• Product comparison across multiple features
• Sports analytics and player comparison
• Market research and competitive analysis
• Risk assessment across different categories
• Quality metrics and KPI dashboards

When analyzing a radar chart, consider the following:

• The area enclosed by each trace indicates overall performance
• Distance from center shows the value for each category
• Irregular shapes indicate strengths and weaknesses across categories
• Overlapping areas show where different traces perform similarly

• Limit the number of variables to 3-8 for readability
• Use consistent scales across all axes
• Arrange variables in a logical order around the chart
• Use different colors or line styles for multiple traces
• Consider the order of variables to avoid misleading visual impressions
• Include clear labels and legends for all traces and axes
