This scatter plot visualizes the relationship between acceleration and horsepower for cars from the auto-mpg dataset. D3’s scaleLinear, axisBottom, and axisLeft functions map the quantitative values, while circles are appended to an SVG container. The code loads CSV data via d3.csv, converts numeric fields, and uses margin-based layout with tick marks and axis labels. Red translucent circles reveal density, with axes formatted using d3.format and a title added manually.
