This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements. The visualization uses React dropdown menus to dynamically switch which measurement attributes are plotted on the x and y axes, with points colored by species. Built with D3.js v5 and rendered as SVG, the code uses `scaleLinear` for axes, `scaleOrdinal` for categorical colors, and `d3.axisBottom`/`d3.axisLeft` to construct the plot. The iris data is loaded via `d3.csv` from a linked gist.
