Better-for-you soda and sparkling water: who sits near whom

Each brand's national Qloo heatmap, re-ranked by percentile within the cells all three carry, as the pair map does. A cell goes to the brand with the highest percentile there and stays blank when none reaches its own top half. 78 of every 100 coloured cells share their leader with most of their neighbours, so these are regions, not scattered points. Three brands, not the whole aisle: with all nine, the brands with the biggest maps decide most cells (see /audit). Simply Pop stands for the prebiotic side: Poppi's map shares only 1,961 cells with Olipop and LaCroix, under the 3,000-cell floor, and Simply Pop shares 4,681.
