This scatter plot visualizes the relationship between vehicle weight and fuel efficiency (MPG) using data from the UCI Machine Learning Repository’s Auto MPG dataset. It uses D3.js with an SVG rendering, where each circle represents a car, with position determined by linear scales for both axes. The code employs `scaleLinear`, `axisLeft`, `axisBottom`, and `extent` for scaling and axes, while `csv()` loads the external dataset. Axis labels and a title are added via SVG text elements, with circles styled in translucent red.
