  • Radar series uses 0.5 fill opacity to balance with grid background
  • Color coordination between grid fill and data series for visual harmony
  • Data structure requires category field (month) and numeric values
  • Chart automatically maintains aspect ratio within container
  • Uses Recharts RadarChart with enhanced visual styling
