This scatter plot visualizes the Iris dataset, showing sepal length on the x-axis and petal length on the y-axis, with each of the three iris species represented by a distinct symbol. A legend identifies the species by their unique shapes. The visualization is built using D3.js v7, leveraging its modular APIs for data parsing, linear scaling, ordinal shape encoding, and axis rendering. The chart draws data points as SVG paths, with axes and labels generated programmatically to provide a clear and interactive view of the dataset's distribution.
