This scatter plot displays the relationship between sepal length and petal length for Iris flowers, with species differentiated by shape. Built with D3 v7, it uses `scaleLinear` for axes, `scaleOrdinal` with `symbolsFill` for categorical shapes, and custom modules for axes and a shape legend. Data is loaded from a CSV file via `fetch` and parsed with `csvParse`, then rendered as SVG paths using the `symbol` generator.
