Chart Configuration

The component supports multiple data series with color coding:

const chartConfig = {
  desktop: {
    label: "Desktop",
    color: "var(--chart-1)",
  },
  mobile: {
    label: "Mobile", 
    color: "var(--chart-2)",
  },
} satisfies ChartConfig

Implementation Notes

Uses stacked areas with shared stackId="a" for proper layering
Legend automatically displays all configured data series with colors
Mobile area renders first for proper stacking order (bottom layer)
Tooltip shows line indicators for both series simultaneously
Area fill opacity set to 0.4 for balanced visibility between overlapping areas
