This chart displays the Iris dataset as a scatter plot, mapping petal length on the x-axis and petal width on the y-axis, with each species assigned a distinct color. The visualization uses D3.v6, loading data via `d3.csv` and rendering marks as SVG circles. It employs `d3.scaleLinear` for axes, `d3.extent` for domain calculation, and `d3.axisBottom` and `d3.axisLeft` for tick marks. Although sepal length and width are parsed, only petal dimensions are plotted, with species color encoded through a switch statement.
