This animated scatter plot visualizes the Iris dataset, cycling through different sepal and petal measurements on the x-axis while plotting sepal length on the y-axis. Points are color-coded by species, with a legend and axis labels updating dynamically. Built with D3 v6, it uses a reusable `scatterPlot` module with `scaleLinear` and SVG rendering. A `setInterval` timer triggers transitions between axes, showcasing the chart’s adaptability to different data dimensions.
