This animated scatter plot cycles through the Iris dataset's four numeric columns, re-mapping the x-axis every two seconds to reveal different pairwise relationships. Using D3.js with the `scaleLinear` and `extent` APIs for axes, `scaleOrdinal` for species-based symbols, and `symbol()` to generate SVG paths, the visualization updates smoothly via `setInterval`. The `scatterPlot` higher-order function manages reusable chart components, while the CSS styles text with the Share Tech font.
