This scatter plot visualizes the relationship between outdoor temperature and ice cream sales, with points colored by an A/B/C rating category. The visualization uses D3 v7 to load CSV data from a GitHub repository, then maps the temperature and sales measurements to a linear scale. Circles are rendered as SVG elements with colors assigned via a switch statement based on the rating grade. Axis labels are styled green in Times New Roman, with rotated temperature text and bottom ice cream sales label, while D3's `axisLeft` and `axisBottom` functions generate the quantitative scales.
