This interactive scatter plot visualizes the relationship between saturated fat (in grams) and sodium (in milligrams) for menu items from six popular fast-food restaurants, using a Kaggle dataset. It shows individual menu items as circles, with the circle size encoding calorie count and color representing the restaurant. Built with D3.js v7, the plot uses `scaleLinear`, `scaleOrdinal`, and `schemeCategory10` to map data values, while a custom tooltip appears on hover. The visualization is responsive, using `@pbruss/responsive-axes` to adapt the axes to the container's dimensions.
