This scatter plot visualizes the relationship between horsepower and weight for various car models, with each circle representing a data point from the auto-mpg dataset. The visualization uses D3 v7’s scaleLinear, axisBottom, axisLeft, and extent functions to map the data onto the SVG canvas. Points are plotted with a fixed radius of 10 pixels, styled with steelblue fill and 0.5 opacity. The chart includes gridlines via tickSize settings and custom formatting for axis tick labels.
