React Expanded Area Chart
Normalized 100% stacked area chart for showing percentage distribution
Sometimes you care about proportions, not raw numbers. This React area chart normalizes everything to 100%, so you can see how each category's share changes over time—even when totals fluctuate wildly. The magic is stackOffset="expand" in Recharts, which handles all the percentage math for you. This chart shows desktop, mobile, and other traffic as slices of the whole, making it obvious when mobile starts eating into desktop's share. Great for market share dashboards, budget allocation views, or any Next.js app where you need to track how the pie gets divided over time.
