This example shows a bubble chart comparing beverage manufacturers by plotting glucose levels on the x-axis and ratings on the y-axis, with bubble size encoding calorie content and color distinguishing maker categories. The visualization uses d3.csv to load tabular data and d3.scaleLinear for the x, y, and bubble radius scales, while d3.scaleOrdinal assigns distinct colors to manufacturers. SVG circles are rendered with d3.selectAll and .join('circle'), and an interactive tooltip appears on mouseover using D3’s event handling. The chart includes labeled axes, a title, and legend ranges for the scales.
