This scatter plot visualizes car sales data by manufacturer, plotting the proportion of sales below 100 units against sales between 100 and 200 units. Each circle represents a manufacturer, colored using a categorical scale with d3.schemeCategory10, with axes labeled and a legend indicating manufacturer names. The visualization uses D3 v7 with SVG rendering, loading data from a remote CSV file via d3.csv, and constructs linear scales (d3.scaleLinear) for both axes to map the numeric fields.
