A grouped scatter plot displays the relationship between sepal length and sepal width for three Iris species, with each species rendered in its own horizontal band. The visualization uses React and D3 v6 to compose scales and axes, with `scaleBand` positioning species groups and `scaleLinear` mapping measurements. SVG circles represent individual flowers from the Iris dataset, and tooltips show exact values. Axis components are built from custom React components, while `d3.csv` loads the data from a remote source.
