This scatter plot visualizes the Iris dataset, mapping petal length and width as x and y coordinates while encoding species through point color (grey, violet, and blue). The visualization uses D3 v6 with SVG rendering, employing `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` for scales and axes. Data is loaded via `d3.csv` from a remote GitHub gist. The code also applies `rx` and `ry` attributes to circles using sepal measurements, creating elliptical points, though the visual effect is subtle due to the fixed radius.
