This animated scatter plot visualizes BMW car sales data, mapping four quantitative attributes—Engine Size, Mileage, Price, and Sales Volume—against each other on dynamic axes. The visualization cycles the x-axis variable every three seconds, using D3.js v6 modules including `scaleLinear`, `axisBottom`, `axisLeft`, and `scaleOrdinal` with `schemeCategory10` for coloring. Data points are rendered as SVG symbols (`symbolCircle`, `symbolDiamond`, `symbolTriangle`, `symbolSquare`) representing fuel types, which are also displayed in a separate legend. The chart updates smoothly via setInterval, re-calling the reusable scatter plot component with new mappings while preserving the y-axis and color encoding.
