A reusable scatter plot displays three numeric attributes—weight, height, and price—from a CSV dataset, letting users switch axes via dropdown menus. Built with D3 v6, it uses `d3.scaleLinear` and `d3.axisBottom`/`d3.axisLeft` to render SVG axes, while `d3.selectAll('circle')` binds data points as steelblue circles. The chart updates by removing and reappending axes and circles on dropdown changes.
