This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements through dropdown menus that select the x and y axes. Built with React and D3 v5, the SVG rendering uses `scaleLinear` for axes, with a `Dropdown` component managing the attribute selections. The data is loaded via `d3.csv` from a remote source, with circles colored uniformly and tooltips displaying the x-axis value in a compact format. The code demonstrates coordinated React state management with D3's functional programming style.
