This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements by selecting which attributes are plotted on the x- and y-axes via dropdown menus. The chart renders data points as SVG circles with tooltips, using D3’s `scaleLinear`, `extent`, and `format` APIs for axes and tick labels. The visualization is built with React, managing state for axis selections, and a custom `useData` hook loads the CSV data using `d3.csv`.
