A scatter plot of the Iris Dataset displays sepal and petal measurements, with dropdown menus allowing users to select which attributes appear on the x- and y-axes. The visualization uses React with D3's `scaleLinear` and `extent` to map data to SVG circles, while axes are rendered via custom `AxisBottom` and `AxisLeft` components. The dropdowns update state to re-scale and re-render the marks dynamically, with formatted tick labels using D3's `format`.
