This scatter plot visualizes the Iris dataset, plotting petal length on the x-axis against sepal length on the y-axis, with each of the three species distinguished by a unique SVG symbol. The code uses D3 v6 APIs including `scaleLinear`, `scaleOrdinal`, `symbol`, `axisLeft`, and `axisBottom`. Data is loaded asynchronously from a CSV via `d3.csv`, and the reusable `scatterPlot` module handles margin configuration and dynamic sizing to fill the browser window.
