This scatter plot visualizes the Iris Dataset, plotting petal length against sepal length for individual flowers. The visualization uses D3 v6 to load the CSV data, scale the x and y axes with `d3.scaleLinear`, and render circles as SVG marks. Axes are added using `d3.axisLeft` and `d3.axisBottom`, with the plot sized to the full browser window. The code demonstrates a clean mapping of data fields to spatial positions.
