This interactive scatter plot visualizes the Iris dataset, comparing sepal length and width across three species. The visualization uses D3.js scaling and axis functions (`scaleLinear`, `axisBottom`, `axisLeft`) to render points colored by species, with hover interactions on the legend highlighting specific species while fading others. The chart includes a title, subtitle, source attribution, and a vertical legend, all styled with BBC-inspired colors. Data loads asynchronously from a CSV file via D3's `csv` parsing, with responsive sizing handled through a `ResizeObserver`.
