This scatter plot displays the Iris Dataset, showing the relationship between petal length and sepal width, with dots colored by species. The visualization loads data asynchronously with `d3.csv` inside a React hook, then renders SVG circles through React components. Scales use `d3.scaleLinear` for both axes and `d3.scaleOrdinal` for categorical colors. Axis components generate ticks and labels using D3’s `scale.ticks()` method, while formatted numbers come from `d3.format`.
