This example renders the classic Iris dataset as an interactive scatter plot, allowing users to explore relationships between sepal and petal measurements by selecting which attributes appear on the X and Y axes via dropdown menus. Built with React components and rendered as SVG, the visualization uses D3's `scaleLinear` and `extent` functions to compute scales from the data, with axes generated by custom `AxisBottom` and `AxisLeft` components. The plot reads data from a CSV file using D3's `csv` utility, and each point displays a tooltip showing its precise value.
