This D3 scatter plot visualizes the Iris Dataset, plotting petal length against sepal length for individual data points. The SVG visualization uses `d3.csv` to load data, `d3.scaleLinear` for axis scaling, and `d3.axisLeft` and `d3.axisBottom` to render axes. Circles are drawn using a `join` operation to bind data attributes to SVG circle elements. The chart is responsive, filling the browser window with margins applied around the plot area.
