This scatter plot displays the relationship between a car’s fuel efficiency (MPG) and its horsepower, using data from a CSV file of auto-mpg measurements. Each circle represents a data point, with position determined by d3.scaleLinear scales for both axes. The visualization includes labeled axes and gridlines, with d3.axisBottom and d3.axisLeft providing ticks. The SVG rendering uses D3 v5 to bind data, append circles, and apply CSS styling for opacity, while the title reflects the dataset’s context.
