This example displays a scatter plot of the Iris dataset, mapping petal length and width on the x- and y-axes while coloring each point by species (setosa, versicolor, virginica) using light blue, light green, and orange. The visualization uses D3 v6, loading data via `d3.csv` from a GitHub Gist, and renders SVG circles with `d3.scaleLinear` for axes and `d3.axisLeft` and `d3.axisBottom` for labeled axes. The code also applies non-standard `rx` and `ry` attributes to circles, though they do not affect the round markers.
