This example visualizes the Iris dataset through three coordinated views: an animated scatterplot, a pie chart of species distribution, and an area chart of sepal measurements. Using d3.csv, d3.scaleLinear, d3.extent, and d3.rollup, it loads data from a GitHub gist and renders SVG graphics. The scatterplot iterates through different x-axis dimensions every few seconds using setInterval, while d3.axisLeft and d3.axisBottom generate axes for each view.
