This animated scatter plot explores the Iris dataset by cycling through different measurement pairs on the x-axis while keeping sepal length on the y-axis. Built using D3.js v6 with SVG rendering, the visualization employs a reusable `scatterPlot` function with `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to create axes. Data points are colored by species using `d3.csv` parsing. A `setInterval` timer updates the plot’s x-value accessor every few seconds, dynamically re-rendering the chart with smooth transitions. The interface includes a species legend and axis labels that update to reflect the currently displayed dimension.
