This animated scatter plot explores BMW car sales data by cycling through four quantitative variables—engine size, mileage, price, and sales volume—on the x-axis every three seconds. Using D3.js v6 modules such as `scaleLinear`, `scaleOrdinal`, and `axisBottom`, each vehicle is rendered as a symbol based on fuel type, colored via `schemeCategory10`. The code constructs a reusable `scatterPlot` component with getter-setter methods, and the animation is driven by `setInterval` calling the SVG selection’s `.call()` method.
