This scatter plot shows the relationship between miles per gallon (x-axis) and vehicle weight (y-axis) for a dataset of cars from the UCI Machine Learning Repository. Each circle represents a car, with the SVG visualization rendered using d3.v6. The code uses d3.scaleLinear for axes, d3.axisBottom and d3.axisLeft for ticks, and d3.extent for data domains, with circles colored green and semi-transparent.
