This scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository, showing the relationship between horsepower and weight for various car models. Each circle is color-coded by the car’s origin, and hovering reveals a tooltip with the car’s name and origin. The visualization is built with D3 v5, using `d3.csv` for data loading, `d3.scaleLinear` and `d3.scaleOrdinal` for scales, and `d3.axisBottom` and `d3.axisLeft` for axes. The SVG rendering includes grid lines, axis labels, and a title.
