This interactive scatter plot visualizes the Iris dataset, comparing sepal length against sepal width across three flower species. The visualization uses d3.scaleLinear, d3.scaleOrdinal, and d3.axisBottom/axisLeft to render the chart, with each species mapped to a distinct BBC color palette. Hovering over the legend items triggers a fade effect on non-selected species using mouseenter/mouseleave events, while the title, subtitle, and source notes are overlaid using SVG text elements.
