This scatter plot shows the relationship between sodium and cholesterol for menu items from six fast food chains, with circle size encoding calorie count and color distinguishing each restaurant. The visualization uses d3.scaleLinear for axes, d3.scaleOrdinal with schemeCategory10 for color coding, and includes interactive tooltips on hover. The chart is rendered responsively using the @pbruss/responsive-axes library, pulling data from a Kaggle fast food nutrition dataset.
