An interactive scatter plot of the Iris flower dataset, showing relationships between sepal and petal measurements. Two dropdown menus let viewers select which attributes map to the x and y axes. The visualization uses React with D3’s `scaleLinear` and `extent` for scaling, and renders SVG circles via the `Marks` component. Data is loaded asynchronously with D3’s `csv` fetching from a GitHub gist, with axes generated by custom `AxisBottom` and `AxisLeft` components.
