This animated scatter plot visualizes the Iris dataset, cycling through four flower measurements on the x-axis while mapping petal width to the y-axis. Points are colored by species—setosa in orange, versicolor in blue, and virginica in black—with a static legend and rotating axis labels. Built with React and D3, the example uses `d3.csv` for data loading, `d3.select` and `selectAll` for SVG rendering, and `setInterval` to trigger periodic axis updates. The code also includes custom circular markers with adjustable radii and a title, demonstrating reusable scatter plot patterns.
