This scatter plot uses the D3.js library (v6) to visualize the relationship between age and height from the heights dataset. It encodes each individual's sex through circle color, with male data points shown in sky blue and female points in orange, while the plot axes are labeled and scaled using D3's linear scale and axis functions. The visualization loads CSV data from an external URL, maps the height and age columns to the x and y axes, and renders the marks as SVG circles.
