A reusable scatter plot visualizes the Iris dataset, encoding species with distinct shapes and colors while mapping petal width against sepal length. Built with d3.v6, it uses d3.scaleLinear, d3.scaleOrdinal, and d3.symbol to render marks as SVG paths. The chart automatically cycles through four axes every 10 seconds, updating the x-value to explore different variable pairs. Dynamic axes and transitions demonstrate a reusable chart pattern inspired by Towards Reusable Charts, with data loaded via d3.csv from a remote gist.
