This example demonstrates a reusable D3.js scatterplot component that visualizes the classic Iris dataset, plotting sepal width against petal width with distinct symbols for each species. The visualization cycles through different column pairings every 200 milliseconds, smoothly updating the axes and points with animation. Built with React and D3 v7, the code uses `scaleLinear` for axes, `scaleOrdinal` and `symbol` for icons, and `axisLeft`/`axisBottom` for rendering. The scatterplot module exposes configurable setters for width, height, data, margins, and symbol size, making it fully reusable.
