This interactive scatter plot visualizes the Iris dataset, encoding four flower measurements across two plots using D3 v6. The main chart maps petal length against petal width, while each point’s radius and fill color—skyblue, lightgreen, or orange—encode sepal length, sepal width, and species via D3 scaleLinear, extent, and a custom marker function. Rendered as SVG circles, the visualization uses axisLeft and axisBottom to generate labeled axes with rotated text, with data loaded asynchronously from a remote CSV via D3’s csv parser.
