This scatter plot displays the Iris dataset, mapping sepal length and sepal width onto a full-window SVG canvas. Each flower is rendered as a circle with a fixed radius of five pixels. The visualization loads the data from a remote CSV file using `d3.csv` and parses numeric fields. It applies `d3.scaleLinear` to compute the x and y scales, and `d3.axisLeft` and `d3.axisBottom` to draw the corresponding axes. The plot fills the entire viewport, with margins applied for axis placement.
