This example presents an interactive scatter plot of the Iris Dataset, featuring dropdown menus that allow users to dynamically select which attributes to display on the x- and y-axes. The visualization uses React to manage state and render SVG elements, with D3.js (d3.v5) providing the scaling, axis generation, and data formatting utilities. Points are rendered as circles with tooltips, and the chart includes labeled axes and a clean, polished aesthetic. The data is loaded asynchronously from a CSV file using D3's `csv` function within a custom `useData` hook.
