This interactive scatterplot displays the Iris dataset, allowing users to explore relationships between sepal and petal measurements by selecting which attribute appears on each axis via two dropdown menus. Built with React and D3 v7, the visualization uses `scaleLinear` and `extent` to compute scales, renders SVG circles for data points, and includes custom `AxisBottom` and `AxisLeft` components for tick marks and labels. The `useData` hook loads the CSV data with `d3.csv`, and the `Marks` component adds tooltip titles for each point.
