A scatter plot of the Iris Dataset displays sepal length against petal length, with points colored by species. A color legend identifies setosa, versicolor, and virginica. Built with D3 v7, the visualization uses `scaleLinear` for axes, `scaleOrdinal` with `schemeCategory10` for colors, and modular functions for axes and legend rendering. Data is loaded from a CSV file and parsed with `csvParse`.
