This scatter plot visualizes the Iris dataset, mapping petal length and petal width for each sample while coloring points by species (setosa, versicolor, virginica). The visualization uses D3 v6 via UNPKG, loading data with `d3.csv`, scaling with `d3.scaleLinear`, and rendering axes with `d3.axisLeft` and `d3.axisBottom`. Circles are appended to an SVG, with fill colors assigned per species and petal dimensions determining x- and y-positions. The chart includes labeled axes and a fixed radius for all points, sourced from a remote CSV hosted on GitHub.
