This example demonstrates a reusable D3.js scatter plot that visualizes Amazon book data, plotting petal width against average rating. It uses the d3.csv function to load and parse the dataset, then employs d3.scaleLinear, d3.axisBottom, and d3.axisLeft to render the axes and circles for each data point. The plot updates its x-axis and circle positions every two seconds by cycling through different numeric columns, driven by setInterval and the scatterPlot function’s configurable accessor methods. The visualization relies on D3 v7 (and v6 in package.json) with SVG rendering and animation.
