This example presents a reusable D3.js scatter plot component built with React and D3 v7. It cycles through different Iris flower measurements (petal width, sepal width, petal length, sepal length) every two seconds, animating the x-axis while the y-axis remains fixed on sepal width. Using `d3.csv` to load the Iris dataset, it leverages `d3.scaleLinear`, `d3.extent`, `d3.axisLeft`, and `d3.axisBottom` to render SVG circles and update axes dynamically. The scatter plot’s configuration is managed through getter/setter methods, allowing flexible parameter changes without redrawing the entire visualization.
