This D3 scatter plot displays the relationship between petal length and sepal length for 150 iris flowers, with each circle positioned by scaled linear axes. It loads the Iris dataset from a CSV file using `d3.csv`, then applies `d3.scaleLinear` with domains from `d3.extent` and ranges based on the window dimensions. The SVG circles are rendered via `d3.select`, `selectAll`, and `join`, while `d3.axisLeft` and `d3.axisBottom` generate the tick marks and labels.
