This scatter plot visualizes the Iris dataset, mapping petal length and width on the x- and y-axes, with circles colored by species. It also encodes sepal length and width as the rx and ry attributes of each circle, creating elliptical markers. The visualization is built with D3 v6, using `csv` to load data, `scaleLinear` for axes, and SVG circles with `attr` bindings. Axis labels and tick styling are customized via CSS and D3's `axisLeft` and `axisBottom`.
