This interactive scatter plot visualizes the Iris Dataset, displaying sepal width against petal length. Each point is colored by species, with a color legend on the right. Hovering over a legend item highlights the corresponding species’ data points while fading others, using React state for interactivity. The visualization is rendered as an SVG using React components and D3 v5 scales, including `scaleLinear` and `scaleOrdinal`, with CSV data loaded via D3’s `csv` function.
