This scatter plot from the CS573 Final Project visualizes the relationship between saturated fat (grams) and sodium (milligrams) for menu items from six popular fast-food restaurants, using circle size to represent calorie count and color to distinguish restaurant brands. Built with D3.js, it uses `scaleLinear` for the axes, `scaleOrdinal` with `schemeCategory10` for color mapping, and the `@pbruss/responsive-axes` library for dynamic resizing. Interactive tooltips display item details on hover, with data sourced from the Kaggle "Fast Food" dataset.
