This scatter plot visualizes the Iris dataset, showing petal length on the x-axis and petal width on the y-axis, with points colored by species (setosa, versicolor, and virginica). It renders as an SVG using D3 v6, employing `d3.csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load data, map scales, and draw axes. The code also applies a custom marker function to assign species-specific colors to each circle. Data is sourced from a raw GitHub CSV file, with page-filling dimensions based on `window.innerWidth` and `window.innerHeight`.
