This visualization shows car sales by month using a reusable scatter plot class. Each dot represents a sale, colored by car model, with jitter applied to reduce overlap among points. Hovering reveals a tooltip with model, sales, and month details. The chart includes x and y axes with labels and a legend. Built with D3 v7, it uses `d3.scaleBand` and `d3.scaleLinear` for positioning, `d3.scaleOrdinal` for colors, and SVG circles with mouse event handlers for interactivity.
