The scatter plot visualizes the Iris dataset, encoding each flower by petal width and sepal length. The axes and displayed data points update every second, cycling through four different column combinations. The visualization uses d3 v6’s scale, axis, and symbol APIs within a reusable ES6 module, applying distinct shapes and colors to differentiate the three species through d3.scaleOrdinal and d3.symbol. Data is loaded from a CSV URL, with rendering handled by SVG paths and animated via setInterval.
