This interactive scatter plot visualizes cereal data filtered to 100 calories, comparing sodium and sugar content. Each circle represents a cereal, with markers colored by rating value: red for ratings below 40, orange for 40–60, and green for ratings above 60. The visualization loads CSV data via `d3.csv` from a GitHub gist, uses `scaleLinear` for both axes, and renders circles as SVG elements with `d3.select` and `join`. Axis labels are positioned with SVG transforms, and the D3 v6 API is loaded directly from UNPKG.
