Empty grids offer reference. Filled grids create zones. This React radar chart applies fill-(--color-desktop) opacity-20 className to PolarGrid with gridType='circle', creating subtle filled rings between circular gridlines. Built with shadcn/ui and Recharts, the tinted background bands help users instantly identify value ranges—data points in outer rings show high values, inner rings indicate lower values. The subtle opacity prevents the fill from overwhelming the data polygon. Perfect for dashboards where quick visual assessment matters more than precise value reading, or when you want to add visual depth to radar charts without cluttering them with heavy grid lines.
