This visualization compares sepal dimensions across iris species using a scatter plot rendered with D3.js v7 and SVG. The chart maps sepal length to the x-axis, sepal width to the y-axis, and color-codes points by species using a BBC-inspired purple palette. An interactive legend with hover fading highlights specific species, while the chart title, subtitle, and source reference Fisher’s Iris dataset. The data loads via `d3.csv` from a remote gist, with axes and labels generated using `d3.axisBottom` and `d3.axisLeft`.
