This bubble chart displays the correlation between average sugar, average weight, and calories per serving for various food items. Circles are positioned by weight and sugar on the x and y axes, while the circle radius encodes calorie count, with a legend showing calorie values. A hover tooltip reveals exact food item, weight, sugar, and calorie details. Built with D3 v7, it loads fooditems.csv and uses `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.schemeCategory10`, and a simple SVG animation on hover to change opacity and stroke.
