This scatter plot uses D3 v7 to visualize the Iris dataset, plotting sepal length against petal length. Each flower is rendered as a shape-coded path marker, with the species determining the symbol type via a d3.symbol generator and ordinal scale. A custom axes module adds labeled x and y axes using d3.axisLeft and axisBottom, while a shape legend provides a key for species, positioned on the right. Data is fetched as CSV and parsed with d3.csvParse.
