This example shows the classic Iris Dataset as an animated scatter plot, cycling through four measured attributes every two seconds to compare sepal and petal dimensions. It uses `d3.scaleLinear`, `d3.extent`, `d3.axisLeft`, and `d3.axisBottom` to render axes and circles in SVG. A reusable chart function with getter/setter methods updates the x mapping in response to a `setInterval` timer, calling the plot again to refresh marks. Styling uses the Share Tech font with a full-window layout.
