This scatter plot visualizes the Iris dataset, mapping sepal length on the x-axis and petal length on the y-axis. Each point’s shape encodes the flower species, with a legend identifying the categories. Built with D3 v7, it uses `scaleLinear`, `scaleOrdinal`, and `symbolGenerator` to render the marks, and custom `axes` and `shapeLegend` modules for labels and legend placement. Data is loaded asynchronously from a remote CSV file and parsed with `csvParse`.
