Database Visualizer Waterfall Chart Infographic

Data visualization infographic titled "Waterfall Chart" using COMPARISON COLUMNS as the dominant visual element, designed to visually emulate a waterfall-style breakdown: a sequence of vertical columns showing how a total changes step by step from a starting value to an ending value. Main chart centered and large, with sharp axis labels and tick marks in English, zero baseline clearly visible, no misleading axis truncation or scale manipulation. Use plausible illustrative values: starting column "Starting Total" = 120, then change columns "Product Sales" +45, "Service Revenue" +18, "Returns" -12, "Operating Costs" -38, "Marketing" -15, "Tax Adjustment" -8, final column "Ending Total" = 110. Show positive changes in deep editorial blue, negative changes in muted slate blue-gray, and total columns in dark navy, connected visually to communicate cumulative movement and breakdown clearly. Y-axis label: "Value (Illustrative Units)" with ticks at 0, 20, 40, 60, 80, 100, 120, 140. X-axis labels in English exactly as rendered: "Starting Total", "Product Sales", "Service Revenue", "Returns", "Operating Costs", "Marketing", "Tax Adjustment", "Ending Total". Add clear value labels on each column, including plus and minus signs for changes, and small tag "Illustrative" near the chart subtitle. Include 4 key insight callouts placed around the chart, each with a headline number, short interpretation in English, and a small icon: 1) " +63 " — "Revenue gains outweigh losses" with upward arrow icon; 2) " -73 " — "Costs and deductions create the largest drag" with minus-circle icon; 3) " 120 to 110 " — "Net result ends below the starting level" with balance-scale icon; 4) " 38 " — "Operating Costs are the biggest single decline" with factory icon. Add a small top subtitle in English: "Step-by-step breakdown of cumulative change". Add a compact legend in English: "Positive Change", "Negative Change", "Total". Add a bottom source/data-note strip in English exactly: "Data note: Illustrative example. Figures shown are for demonstration only unless user-supplied sourced data is provided." Visual style: retro 1970s magazine charts, editorial blue & cream palette, warm cream paper background, slightly off-register print texture, bold serif title with clean sans-serif labels, restrained vintage gridlines, nostalgic but precise. Overall mood: analytical, stylish, trustworthy, editorial. 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.
