Design Organizational Structure Online Heatmap Donut Infographic

Data visualization infographic titled "Heatmap Example" using a PIE / DONUT (composition) chart as the dominant visual element to show inequality clearly. Create a large central donut chart with 6 segments of highly uneven size to emphasize concentration: "Top Zone" 52%, "Upper-Mid Zone" 18%, "Middle Zone" 12%, "Lower-Mid Zone" 9%, "Low Zone" 6%, "Minimal Zone" 3%. Render precise English labels directly on or around the donut with clean leader lines, crisp percentage markers, and a neat outer measurement ring with evenly spaced tick marks from 0% to 100% in 10% steps. Include a small supporting mini heatmap panel beside the donut, labeled "Intensity Grid", showing darker cells clustered in one corner and lighter cells elsewhere to reinforce the inequality theme, but keep the donut as the main visual. Add 4 key insight callouts with small retro icons: 1) headline number "52%" with interpretation "More than half is concentrated in one segment" and a small spotlight icon; 2) headline number "70%" with interpretation "Top two zones dominate the composition" and a small stacked-bars icon; 3) headline number "9x" with interpretation "Largest segment is nine times the smallest" and a small scale icon; 4) headline number "18%" with interpretation "Middle and lower tiers remain comparatively thin" and a small grid icon. Add a compact legend in English with exact labels "Higher intensity" and "Lower intensity". Include a small source / data-note strip at the bottom reading "Data note: Illustrative example only. Figures are illustrative and not based on a cited external dataset." Use retro 1970s magazine charts style, editorial blue & cream palette with deep navy, faded cobalt, powder blue, warm cream, muted ink outlines, subtle paper texture, slightly aged print feel, bold geometric headings, and elegant editorial spacing. Ensure sharp axis labels and tick marks, balanced margins, no misleading scale manipulation, and clear hierarchy. 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.
