This interactive scatter plot visualizes the Iris flower dataset using React and D3.js. Two dropdown menus let users select which quantitative attributes (sepal length, sepal width, petal length, petal width) to map to the x and y axes. The plot renders circles using SVG, with axis ticks and labels via the custom `AxisBottom` and `AxisLeft` components. The data is loaded asynchronously from a CSV file using D3’s `csv` function, and scales are computed with `scaleLinear` and `extent`.
