This fork of a D3 bubble chart compares breakfast cereals by calories on the x-axis, weight on the y-axis, and rating as the bubble radius. Each circle is colored by manufacturer using the `d3.scaleOrdinal` with `d3.schemeTableau10`. The visualization includes custom legends for bubble size and manufacturer colors, rendered as SVG elements built with `d3.csv` data loading and `d3.axisBottom` and `d3.axisLeft` scales. Data comes from a CSV file hosted on GitHub.
