Histogram Looker Sankey Diagram Donut Infographic

Data visualization infographic titled "Sankey Diagram Example" using a PIE / DONUT composition as the dominant visual element to show contrast between major flow categories, with a large retro-styled donut chart in editorial blue and cream palette, subtle 1970s magazine print texture, clean vector geometry, and sharp English labels. Main chart: donut with clearly separated segments labeled "Input A — 42%", "Input B — 28%", "Input C — 18%", "Losses — 12%", with crisp outer guide lines, English legend, precise percentage labels, and a small secondary inset mini-flow illustration to hint at sankey logic without overtaking the donut. Include a neat comparison ring or inner annotations highlighting contrast between largest and smallest shares. Add sharp axis-style annotation guides and tick-marked percentage scale around the chart perimeter in English for readability, with no misleading truncation or scale manipulation. Include 4 key insight callouts with small icons: 1) headline number "42%" with text "Largest share dominates the total flow" and a simple arrow icon; 2) headline number "12%" with text "Losses remain the smallest component" and a warning-drop icon; 3) headline number "14 pts" with text "Gap between Input A and Input B shows clear contrast" and a split-bars icon; 4) headline number "70%" with text "Top two inputs account for most of the composition" and a combined-circle icon. Add a small source / data-note strip at the bottom reading "Data note: Illustrative example only. Figures are illustrative unless sourced by the user." Use retro 1970s magazine charts style, editorial blue & cream palette with muted navy, warm cream background, faded teal accents, minimal rust highlight, confident editorial mood, balanced negative space, bold title, concise subtitles, 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.
