This interactive scatter plot visualizes the Iris dataset, showing species classifications through color-coded points. Hovering over the legend highlights the selected species and fades the others, while raising those points to the top for emphasis. Built with D3 v7, it uses scaleLinear for axes, scaleOrdinal for species colors, and svg.selectAll joins with enter/update/exit patterns for dynamic rendering. The chart includes customized BBC-style axes, labels, and a source attribution.
