A reusable scatter plot displays car price versus miles per gallon, with each dot representing a vehicle and colored via a random Tableau10 palette entry. The chart is built as a configurable JavaScript function using D3 v7, employing `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to render axes and SVG circles for data points. Data loads from a remote CSV file via `d3.csv` with `d3.autoType`, and tooltips show car model and brand on hover. The visualization highlights the relationship between vehicle cost and fuel efficiency across the Cars dataset.
