This interactive scatter plot visualizes the Iris dataset, displaying sepal and petal measurements for three flower species. Users can switch between different measurement combinations using buttons, with each selection triggering an animated update of the axes and data points. The visualization uses D3.js v6 with SVG rendering, employing d3.scaleLinear for scales, d3.axisBottom and d3.axisLeft for axes, and a custom tooltip that appears on mouseover to show the species and exact values for each point.
