This scatter plot visualizes the Iris Dataset, plotting petal length against sepal length for individual flowers. The visualization uses D3 version 6, loading the data via the `csv` function and parsing numeric fields. The code employs `scaleLinear` to map data domains to pixel ranges, `extent` to calculate domains, and `axisLeft` and `axisBottom` to render the y- and x-axes. Data points are drawn as SVG circles using the `.join` operator, while axis labels are added as SVG text elements.
