This scatter plot visualizes the relationship between MPG and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set, with each circle representing a vehicle. The chart uses a blue, semi-transparent point encoding to reveal density and patterns across the axes, labeled “MPG” and “Weight.” Built with D3 v5, the code employs `scaleLinear` for both axes, `axisBottom` and `axisLeft` for tick rendering, and `csv` to load and parse the data. The SVG rendering includes custom margins, tick lines, and axis labels styled via CSS.
