This interactive scatter plot visualizes the Iris dataset, allowing users to select which flower measurements (sepal length, sepal width, petal length, petal width, or species) appear on each axis via dropdown menus. Built with React and D3 v5, it uses `scaleLinear` from d3 for axis scaling, `extent` for domain computation, and `csv` for data loading. SVG circles represent individual iris samples, with D3 tick marks and labels rendered as React components, and each point includes a tooltip showing its x-axis value.
