This scatter plot shows the relationship between calories and protein content across fast food items from various restaurants. Each circle represents a single menu item, plotted with its calorie count on the x-axis and protein grams on the y-axis. The visualization uses d3.scaleLinear to map data values to pixel positions, with circles appended to an SVG canvas at 4px radius. Calorie and protein values are parsed from the CSV data using d3.csv, and d3.axisBottom and d3.axisLeft render the axes with labeled text annotations.
