This scatter plot visualizes a small dataset of six people, mapping their height on the x-axis and weight on the y-axis, with each point colored blue for males and pink for females. The chart uses D3 v6’s `scaleLinear` for continuous axes, `axisBottom` and `axisLeft` for tick labels, and SVG circles for marks. While the code also computes age and height for potential `rx` and `ry` attributes, the rendered circles retain a fixed radius of 7 pixels, so these extra variables do not affect the visual encoding.
