A scatter plot of the Iris dataset renders four numeric attributes as x- and y-coordinates, with points colored by species using D3's `scaleOrdinal`. React dropdowns let viewers choose which attributes to compare, while numeric axes are generated with `scaleLinear` and annotated via `AxisBottom` and `AxisLeft` components. The visualization uses D3 v7 within a React framework, rendering SVG circles with tooltips using the `title` element.
