A bubble chart compares beverage manufacturers, plotting glucose levels along the x-axis against ratings on the y-axis. Each bubble’s radius represents calorie content, while its color identifies the manufacturer brand. The chart includes interactive tooltips on mouseover and a legend for both bubble size and color categories. Built with D3 v7, it uses `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.axisBottom` to render the SVG elements; the data is loaded from a CSV file and animated through hover transitions.
