This animated scatter plot visualizes the Iris flower dataset, cycling through four feature combinations on the x-axis while keeping sepal length on the y-axis. Data points are colored by species, and a legend identifies each category. The visualization uses D3 v6 with SVG rendering, employing reusable chart functions and `setInterval` to update the axis scales dynamically. The code leverages D3's `csv` loader, `scaleLinear`, and `axisBottom` APIs to construct the interactive graph.
