This interactive scatter plot visualizes the Iris dataset, mapping sepal length to the x-axis and petal length to the y-axis while using distinct symbols to represent each species. Built with D3 v7, it employs `scaleLinear` for the axes, `scaleOrdinal` with `symbolsFill` for shape encoding, and `symbol` generators to draw the marks. A custom shape legend displays the species categories, and the data is fetched as CSV and parsed with `csvParse`.
