This visualization is a scatter plot of the Iris dataset, showing sepal length on the x-axis and petal length on the y-axis. The plot uses different point shapes, drawn via D3's `symbol()` with `symbolsFill`, to represent the three Iris species, with a custom legend on the right side. The axes are created using D3's `axisLeft` and `axisBottom`, and the data is fetched from a remote CSV and parsed with `csvParse`. The visualization uses D3's scales (`scaleLinear`, `scaleOrdinal`) and is rendered as an SVG, with margins and labels for both axes and the legend.
