This interactive scatter plot visualizes the Iris dataset by mapping petal length and petal width to the x- and y-axes, with each point colored according to species. The visualization renders as an SVG using D3 v6, loading data via `d3.csv` from a GitHub gist. It employs `scaleLinear` and `extent` for axis scaling, along with `axisLeft` and `axisBottom` to display tick marks. The code also defines a `marker` function that assigns colors to different species, though the actual color mappings are not fully implemented.
