This example presents an animated scatter plot of the Iris flower dataset, cycling through four measurement dimensions every three seconds. It showcases a reusable D3 chart module where data points transition smoothly between axes using d3.transition, with circles entering, updating, and exiting via D3’s data join. The visualization leverages d3.scaleLinear, d3.extent, d3.axisLeft, and d3.axisBottom to map values, while SVG rendering and CSS styling with the Share Tech font complete the presentation. The code demonstrates animated axis updates and staggered circle movements.
