This example demonstrates a classic boxplot visualization of a numeric dataset, highlighting the median, interquartile range, whiskers, and any potential outliers. The chart computes the five-number summary using `d3.quantile` and draws the box, median line, and whiskers as SVG shapes, with circles marking values beyond 1.5 times the interquartile range. The y-axis is rendered with `d3.axisLeft`, and the scaling is handled by `d3.scaleLinear`. The dataset is hardcoded in the script, and the entire visualization is built with React and D3 v5, outputting to SVG.
