This animated scatter plot visualizes the Iris dataset, showing the relationship between sepal and petal measurements across three species, with each species distinguished by a color-coded legend. The visualization cycles through different column pairings every two seconds using `setInterval`, updating the x-axis scale and circle positions. Built with D3 v6, the code uses `d3.scaleLinear`, `d3.extent`, `d3.axisLeft`, and `d3.axisBottom` to render the SVG circles and axes. Data is loaded from a CSV file using `d3.csv`, with species colors mapped via `d3.scaleOrdinal` and a custom `scatterPlot` function managing the reusable chart logic.
