This animated scatter plot visualizes Iris flower measurements, cycling through different feature combinations on the x-axis while plotting petal width against sepal length. The visualization uses D3.js v6 with SVG rendering and animation, leveraging scales (scaleLinear), axes (axisLeft, axisBottom), and data loading via d3.csv. Circles are colored by species (red, violet, orange) with a legend, and the plot updates every few seconds to display different variable pairings from the Iris dataset.
