This interactive scatter plot visualizes the Iris dataset, mapping petal length against sepal width for individual flowers. Using React and D3 v5, the SVG-based visualization employs `d3.scaleLinear` for both axes and `d3.scaleOrdinal` for species-based coloring. Hovering over the color legend highlights the corresponding species by fading other points to 30% opacity, while native SVG `<title>` elements provide basic tooltips. The chart includes labeled axes and a species legend, with data loaded asynchronously via D3’s `csv` parser.
