This scatter plot visualizes the Iris dataset, plotting petal length against sepal length for individual flowers. Built with D3 v6, the visualization uses `d3.csv` to load data, `d3.scaleLinear` for axis scaling, and `d3.axisLeft` and `d3.axisBottom` to render axes. The SVG canvas fills the browser window, with each data point drawn as a circle using D3's `selectAll` and `join` operations.
