This example shows a stacked bar chart of fruit consumption over time, using d3.v3 with SVG rendering and React integration. The visualization displays four categories (redDelicious, mcintosh, oranges, and pears) as stacked layers, with a tooltip revealing individual segment values on mouseover. The code uses d3.layout.stack() to transpose data, d3.time.format for year parsing, and d3.svg.axis for both x and y axes, building the chart with svg rect elements and a custom legend.
