This example visualizes the Iris Dataset as a scatter plot, mapping petal length to the x-axis and sepal length to the y-axis. Using D3 v6, it loads data via `d3.csv`, applies linear scales with `scaleLinear` and `extent`, and renders circles as marks. Axes are drawn with `axisBottom` and `axisLeft` in an SVG container. The plot fills the entire window and displays all 150 samples without color or categorical encoding.
