This example presents an interactive scatter plot of the classic Iris flower dataset, using SVG circles to visualize relationships between different measurements like petal length and sepal length. Built with React and D3 v3, the visualization cycles through four data columns every two seconds, smoothly animating the transition of points across axes via D3’s `transition.attr` method. The reusable `scatterPlot` function leverages D3 scales (`scaleLinear`), axes (`axisLeft`, `axisBottom`), and data joins to dynamically update the visualization. The code loads data from a remote CSV using `d3.csv` and adapts to the browser viewport dimensions.
