This reusable scatter plot visualizes car sales data, showing the relationship between horsepower and price, with color encoding car make and bubble size representing mileage. The chart includes interactive tooltips that display detailed values on hover. Built with D3 v7, it uses `d3.scaleLinear` for axes, `d3.scaleSqrt` for bubble size, and `d3.scaleOrdinal` with `schemeTableau10` for categorical colors. Data comes from a Kaggle CSV loaded via `d3.csv`, rendered as SVG elements within a reusable component function.
