This interactive scatter plot visualizes the Iris dataset, allowing users to compare any two flower measurements via dropdown menus while color-encoding points by species. Built with React and D3 v5, it uses `scaleLinear` for axes, `scaleOrdinal` for the categorical color scale, and renders SVG circles through React components. The chart includes a custom color legend and axis components, with data loaded asynchronously from a CSV using D3's `csv` parser.
