This scatter plot visualizes the relationship between total bills and tips in restaurant data from the tips.csv file. The d3.scaleLinear and d3.axisBottom/axisLeft APIs map the data to SVG circles, with color distinguishing male (blue) and female (magenta) customers. Axis labels and a title are added using d3-selection methods, while the styling from styles.css applies opacity and typography. The data originates from the UCI Machine Learning Repository’s Auto MPG set, though the actual plotted variables come from a tips dataset.
