This D3 scatter plot visualizes the Iris Dataset, mapping petal length on the x-axis and sepal length on the y-axis. It uses `d3.csv` to load and parse the data, then `d3.scaleLinear` with `d3.extent` to compute domains for both axes. Circles are rendered in an SVG canvas via `selectAll('circle').join('circle')`, with axes added using `axisLeft` and `axisBottom`. The plot fills the browser window, with a tick font size of 24 pixels.
