This dynamic scatter plot visualizes the Iris dataset, with points representing individual flowers. It uses a reusable D3 module with `scaleLinear`, `axisLeft`, and `axisBottom` to render axes in SVG. Every two seconds, the x-axis attribute cycles through petal width, sepal width, petal length, and sepal length, automatically updating the scales and circles. Data is loaded via `d3.csv` from a GitHub gist, and the chart animates through these four feature comparisons.
