This scatter plot visualizes the Iris dataset, plotting petal length on the x-axis against sepal length on the y-axis for individual flowers. The visualization uses D3.js to load CSV data via `d3.csv`, create linear scales with `scaleLinear`, and render SVG circles as data points. Axes are generated using `axisBottom` and `axisLeft` and positioned within a margin-based layout. The chart fills the browser window through dynamically computed width and height, with the rendered SVG scaling to the viewport.
