This interactive scatter plot visualizes the Iris dataset, showing the relationship between petal and sepal measurements for three flower species (setosa, versicolor, and virginica) using color-coded circles. Built with D3 v6, the visualization cycles through different measurement combinations every 2 seconds using setInterval, updating the x-axis and scatter positions. The implementation uses d3.scaleLinear for axes, d3.scaleOrdinal for species colors, and d3.axisLeft/d3.axisBottom for rendering axes in SVG. Data loads from a GitHub Gist CSV via d3.csv, with circles animated through D3's join pattern.
