This scatter plot shows the relationship between calories and protein content in fast food items, with each circle representing an individual menu item. The visualization uses d3.csv to load the dataset, d3.scaleLinear for both axes, and SVG circles with steelblue fill to encode the two nutritional variables. Restaurant names and item details from the dataset are not shown, but the chart includes labeled axes and a title. The code applies opacity to reveal overlapping points across the 147 items in the dataset.
