This scatterplot visualizes the Iris dataset, comparing sepal length and width across three species—setosa, versicolor, and virginica—using distinct BBC-inspired colors. The chart includes labeled axes, a title with subtitle, a source attribution, and an interactive legend that dims non-hovered species when moused over. Built with d3.v7, it loads CSV data via `d3.csv`, maps dimensions through scales like `scaleLinear` and `scaleOrdinal`, and renders points as circles with configurable styling, while the legend uses `mouseenter` and `mouseleave` events to trigger the hover fade effect.
