This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set. Each semi-transparent circle represents a car, with positions determined by linear scales for both axes, using data parsed from a CSV file. The visualization uses d3.scaleLinear, d3.axisBottom, and d3.axisLeft to render axes with grid lines, while SVG circles are appended via d3 selection and data joins. Axis labels and a title are drawn as SVG text elements, with styling applied via CSS.
