This interactive scatter plot visualizes the Iris dataset, mapping sepal length to the x-axis and petal length to the y-axis, with species encoded through distinct point shapes. The visualization uses D3 v7's `scaleOrdinal` and `symbolsFill` to assign different symbol types to each species, with a custom legend showing the shape-to-species mapping. The React-based application fetches the CSV data from a GitHub repository, parses it using `csvParse`, and renders the plot with axes and labels defined in the `axes.js` component.
