This example shows an interactive boxplot of a small dataset with two columns, allowing users to toggle between a linear and a log10 scale for the y-axis. The visualization uses D3 v5 within a React framework, rendering SVG elements with animated transitions. Key D3 APIs include `scaleLinear`, `scaleLog`, `scaleBand`, `quantile`, and axis components like `axisBottom` and `axisLeft`. The code computes quartiles and whiskers, and removes outlier circles when switching scales. A tooltip appears on hover over the boxplot.
