This example visualizes Olympic medal counts for nine countries as a scatterplot, with gold medals mapped to the x-axis and silver medals to the y-axis. Each circle’s radius scales with the square root of the Euclidean distance between the two medal values, while its fill color blends the gold and silver counts into an RGB value. The SVG is built dynamically using D3 version 6’s data join, with `selectAll`, `data`, and `enter` appending circles, and the dataset is hardcoded within the HTML script rather than loaded from an external file.
