This interactive scatter plot visualizes the Iris dataset, coloring points by species (setosa, versicolor, virginica) and animating the x-axis through four measurement columns on an interval. Built with d3.v6, it uses `scaleLinear`, `axisBottom`, `axisLeft`, and `join` to render SVG circles and axes, while a custom legend and rotated axis label are appended directly. The chart cycles the x-axis variable, updating scales and re-rendering marks each second.
