A bubble chart compares beverage manufacturers across three variables: glucose levels on the x-axis, rating on the y-axis, and caloric content encoded by both bubble size and color. The visualization uses d3.scaleLinear for axes and bubble radius, d3.scaleOrdinal for the categorical color mapping, and SVG circles with mouseover tooltips. Data from a CSV file is loaded via d3.csv, with animation via d3 transitions on the tooltip.
