This visualization compares sepal length and width across Iris species using a scatter plot, with each species differentiated by color and an interactive legend that highlights points on hover. It renders vector graphics via a configurable pipeline, utilizing d3’s `csv`, `scaleLinear`, `scaleOrdinal`, `axisBottom`, and `axisLeft` functions. The data comes from Fisher’s Iris dataset, loaded dynamically from a gist URL. Styling follows a BBC color theme, with points, axes, and labels configured through a separate theme object.
