This scatter plot visualizes the Iris dataset, displaying petal length on the x-axis and petal width on the y-axis, with each point colored by species (skyblue for setosa, lightgreen for versicolor, and orange for virginica). The visualization uses D3 v6 APIs including `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to map data coordinates and render SVG circles with a fixed radius. Data is loaded asynchronously from a CSV file hosted on GitHub via `d3.csv`, with additional sepal measurements parsed but not directly plotted. The chart fills the browser window and includes rotated axis labels for clarity.
