This scatter plot visualizes the relationship between calorie content and price for menu items, with each point colored by category using a D3 ordinal color scale. The visualization uses `d3.scaleLinear` for both axes and `d3.axisBottom`/`d3.axisLeft` for ticks. Data is loaded asynchronously from a GitHub gist via `d3.csv`, then mapped to SVG circles with `d3.select` and `append`. The SVG rendering includes styled axes and labeled dots within a fixed 460×400 viewport.
