This scatter plot visualizes the Iris dataset, plotting petal length against petal width and coloring each point by species (setosa, versicolor, or virginica). The visualization uses D3 v6 to load CSV data, apply linear scales with `scaleLinear`, and render circles with `select` and `join`. Interactive axes are generated via `axisLeft` and `axisBottom`, with labels for both dimensions. The plot fills the browser window, using an SVG canvas, and includes a legend-like color mapping for the three species.
