This visualization presents three coordinated views of a cereal dataset featuring 77 products. A bar chart displays average calories by manufacturer, a scatter plot examines the relationship between sugar content and consumer ratings with points colored by cereal type, and a multi-series chart combines average calories as bars with average rating as a line. The SVG charts are rendered using D3 v7, with axes, grids, and tooltips implemented through D3's SVG and event handling APIs. The code styles bars, lines, and dots using CSS custom properties.
