This interactive scatter plot visualizes the Iris dataset, mapping sepal length and petal length while encoding species through distinct point shapes. The chart includes labeled axes (Sepal Length, Petal Length) and a custom shape legend in the upper right. Built with D3 v7, it uses `scaleLinear` for axes and `scaleOrdinal` with `symbolsFill` for shape mapping. The visualization loads data asynchronously via `csvParse` from a GitHub-hosted CSV, then densely renders marks using `path` elements and the `symbol()` generator.
