This scatter plot visualizes the Iris dataset, showing petal length against petal width for three iris species, with each species color-coded as skyblue, lightgreen, or orange. The visualization uses D3 v6 to load CSV data, apply linear scales, render SVG circles with axis labels, and position points within a full-window viewport. The code implements axes, margin-based layout, and color mapping through a switch function, while reading data from a GitHub-hosted CSV file.
