This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements through dropdown menus that select which attributes appear on the x- and y-axes. The visualization is built with React and D3 v5, using `d3.scaleLinear` for axes, `d3.extent` to compute domains, and `d3.csv` to load the data. SVG circles represent individual flowers, with native `<title>` tooltips showing coordinates. The interface uses React `useState` hooks to manage selected attributes, while reusable components render axes and marks.
