A scatter plot of the Iris dataset, rendered as SVG circles, visualizes relationships between sepal and petal measurements. The visualization features interactive dropdown menus, built with React and the `react-dropdown` component, that let users select which attribute maps to the x- and y-axes. The chart uses `d3.scaleLinear` and `d3.extent` to compute scales from the data, which is loaded as CSV via `d3.csv`. Axis components render tick marks and labels using SVG elements.
