This interactive scatter plot visualizes the Iris dataset, plotting petal width against sepal length. It animates through all four numeric measurements by updating the x-axis every ten seconds, cycling through petal_width, sepal_width, petal_length, and sepal_length. The plot uses D3 v6's `scaleLinear`, `scaleOrdinal`, and `axisBottom` APIs to render SVG symbols, with distinct shapes and colors for each species. Data is loaded from a CSV file via `d3.csv`, and the visualization updates dynamically by re-calling the scatter plot function with new x-value mappings.
