A scatter plot displays yearly sales data as steelblue circles, with orange highlighting on hover. The chart maps the Year and Sales fields from a CSV file onto linear scales, with axes labeled accordingly. Built with D3 v7 in a React environment, the visualization uses `d3.csv` to load data, `scaleLinear` and `extent` for scaling, and `axisBottom`/`axisLeft` for axis generation, rendered as SVG circles sized at a fixed radius.
