This interactive scatter plot explores the Iris dataset, displaying sepal length against petal width as animated circles. It cycles through different column pairings every two seconds, letting viewers see relationships between all four flower measurements. The visualization uses D3 v6’s modular API, including `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`, to render axes and marks in SVG. Data is loaded from a CSV file, and the chart is built as a reusable function with configurable width, height, margins, and radius.
