This interactive scatter plot visualizes the Iris dataset, comparing sepal length and sepal width across three flower species using distinct BBC-style colors. Hovering over the legend highlights points of the selected species while dimming others. Built with D3.js, it uses `scaleLinear`, `scaleOrdinal`, `axisBottom`, and `axisLeft` to render the visualization, with data loaded via `d3.csv` from Fisher's Iris dataset.
