This interactive scatter plot visualizes Fisher’s Iris dataset, allowing users to switch the x-axis attribute among sepal and petal measurements via a React dropdown menu. The visualization uses D3 v5’s `scaleLinear` and `extent` functions to map data to SVG coordinates, with axes rendered as custom React components. Stylized with the Poppins font and teal circular marks, hovering reveals tooltips formatted with D3’s `format`. The y-axis remains fixed on sepal width while the x-axis changes dynamically.
