This scatter plot visualizes the Iris dataset, plotting petal length against sepal length for each flower sample. The visualization uses a D3 v6 SVG rendering with circles positioned along linear scales. Points are intentionally rendered in a single color, with tooltips revealing the exact coordinate values on hover. The code leverages `d3.csv` for data loading, `d3.scaleLinear` for axis scaling, and `d3.axisLeft` and `d3.axisBottom` for chart axes. The implementation dynamically sizes the plot to the browser window using `window.innerWidth` and `window.innerHeight`.
