This example displays a scatter plot of BMI data, plotting each individual’s weight against their height. The visualization uses red and yellow circles to differentiate between male and female data points, with labeled axes for both dimensions. The code loads CSV data from a GitHub gist using `d3.csv`, maps the parsed height and weight values through `d3.scaleLinear` and `d3.extent`, and renders circles as SVG elements. It leverages D3 v6’s `select`, `axisLeft`, and `axisBottom` APIs to generate the chart, with a fixed radius for each point and axis tick labels styled at 24 pixels.
