This interactive scatter plot visualizes the Iris dataset, with dropdown menus allowing users to select the attributes mapped to the x- and y-axes. The React application uses D3.js scale functions, including `scaleLinear` and `extent`, to compute domains and ranges for the SVG circles representing each iris flower. The D3 `csv` loader asynchronously fetches and parses the dataset from a GitHub gist, while the `react-dropdown` component provides the menu interface, and axis ticks are rendered with D3’s scale methods.
