This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository's Auto MPG data set. Red, semi-transparent circles represent individual cars, revealing the general trend and density of data points across the two quantitative axes. The visualization is built with D3 v5, using an SVG rendering approach. The code constructs linear scales for both axes, applies nice rounding, and renders grid lines through D3's axis generators, with labels applied via text elements.
