Waterfall Chart Small-Multiples Dashboard for Sankey Excel

Data visualization infographic titled "Waterfall Chart" using SMALL-MULTIPLES GRID as the dominant visual structure, with each panel containing a clear waterfall breakdown chart to show how a starting value changes through sequential positive and negative contributions to an ending value. Compose a 2x2 or 3x2 grid of mini waterfall charts, each panel labeled in English with exact text such as "Revenue Bridge", "Cost Bridge", "Profit Bridge", "Cash Flow Bridge", using realistic plausible illustrative numbers only. In each panel, render vertical waterfall steps with distinct colors for increase, decrease, subtotal, and final total, sharp axis labels and tick marks in English, baseline starting at zero with no misleading axis truncation or scale manipulation. Suggested axis text: x-axis label "Components", y-axis label "Amount (USD mn)". Example panel values: starting total 120, +35, -18, +22, -9, final total 150; another panel 200, -40, +15, -25, +30, final 180; another panel 90, +20, -12, +8, +14, final 120; another panel 160, -22, -18, +26, +12, final 158. Mark numbers and metrics as illustrative where appropriate, with small labels such as "Illustrative" near panel subtitles or notes. Add 4 key insight callouts around the grid, each with a headline number, a short interpretation in English, and a small icon: "150" with "Largest ending total after net gains" and upward arrow icon; "-40" with "Biggest negative step appears in cost-heavy bridge" and warning/down icon; "+35" with "Strongest positive contribution in the revenue bridge" and plus icon; "4 panels" with "Small multiples make category-by-category breakdowns easy to compare" and grid icon. Include a compact legend in English with exact labels "Increase", "Decrease", "Subtotal", "Final total". Add a small SOURCE / DATA-NOTE strip at the bottom in English with exact text: "Data note: Illustrative example. Figures are for visual demonstration only unless user-supplied sourced data is provided." Visual style: dark dashboard, FT pink & navy palette, deep navy background, muted charcoal panel cards, FT-inspired pink highlights, soft coral for decreases, pale gridlines, crisp white and light-gray typography, subtle glow for dashboard polish, analytical and premium mood. Include editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no fake authoritative sources cited, no watermarks Numbers labeled "illustrative" unless the user supplied specific sourced data. No fake authoritative sources cited (do not invent "Source: Reuters 2025" — use "Illustrative example" instead). No misleading axis truncation or scale manipulation.
