This scatter plot displays the relationship between sepal length and petal length for Iris flowers. The visualization maps petal length on the y-axis, sepal length on the x-axis, with species differentiated by distinct symbol shapes. A legend indicates which shape corresponds to each species. The code uses d3's `scaleLinear`, `scaleOrdinal`, `symbol`, `axisLeft`, and `axisBottom` APIs to construct the plot. Data is loaded from a remote CSV file containing the classic Iris dataset, fetched and parsed with `fetch` and `csvParse`.
