This visualization displays the Iris dataset as a scatter plot, mapping petal length on the x-axis and petal width on the y-axis while coloring each point by species. Using D3 v6, it loads CSV data via `d3.csv`, applies `scaleLinear` for both axes, and renders circles with `d3.selectAll` and `.join`. Axis labels are added via `axisLeft` and `axisBottom`, with rotated text for the vertical label. Despite naming variables for sepal length and width, only petal dimensions are plotted, while species hues are hardcoded for setosa, versicolor, and virginica.
