This scatter plot visualizes the Iris dataset, mapping sepal length on the x-axis and petal length on the y-axis, with categorical species encoded through different point shapes. The visualization uses D3.js v7 to render the plot, with axes generated via `axisLeft` and `axisBottom` from the `d3` module. A custom shape legend explains the species-to-symbol mapping, built using `d3.symbol()` and `d3.symbolsFill`. Data is fetched as CSV and parsed with `d3.csvParse`, with numeric columns converted for scaling. The implementation demonstrates modular D3 components for reusable chart construction, including separate `axes.js` and `shapeLegend.js` modules composed within the main `scatterPlot.js` layout.
