A line chart with a custom label
A React line chart with custom label formatter displaying category names instead of values at each data point using shadcn/ui and Recharts
Numbers are useful, but sometimes you need to show what the data represents. This React line chart uses LabelList with a custom formatter function to display browser names (Chrome, Safari, Firefox) instead of visitor counts above each point. Built with shadcn/ui and Recharts, the formatter prop transforms dataKey values through chartConfig labels. This creates self-documenting charts where category identity appears directly on the visualization—perfect for categorical data like market share by brand, feature usage by tier, or performance by configuration where the what matters as much as the how much.
