This interactive scatter plot visualizes the Iris dataset, allowing users to dynamically select which flower measurements appear on the x- and y-axes via dropdown menus. The visualization is built with React and rendered as SVG, using D3 v5 scale functions like `scaleLinear` and `extent` for scaling and axis generation. Data is loaded asynchronously with `d3.csv` from a GitHub-hosted CSV file. Each point represents an iris specimen, with native SVG `<title>` elements providing hover tooltips that display precise values.
