This scatter plot visualizes the Iris dataset, showing sepal length against petal length with each of the three species distinguished by different symbols. The visualization uses d3.v7 to create a dynamic scatter plot with axes, a shape legend, and smooth transitions as data loads. It employs d3.scaleLinear for positioning, d3.scaleOrdinal with symbolsFill for shape encoding, and d3.symbol to render the marks. The data is fetched from a raw CSV file hosted on GitHub and parsed using d3.csvParse.
