Superset Data Tree Map Example Outlier Column Infographic

Data visualization infographic titled "Tree Map Example" using COMPARISON COLUMNS as the dominant visual element. Create a vertical column chart that compares category sizes as an illustrative example for hierarchical data, designed to highlight one surprising outlier. Use 8 columns with clear English labels: "Category A", "Category B", "Category C", "Category D", "Category E", "Category F", "Category G", "Category H". Use realistic plausible illustrative values: 18, 22, 19, 24, 21, 23, 20, 57. Show a full honest y-axis from 0 to 60 with sharp tick marks every 10 units, labeled in English: "Value" and x-axis labeled "Categories". Make "Category H" the obvious outlier with stronger blue emphasis while the other columns use coordinated muted blue and cream tones. Add a subtle subtitle in English: "Illustrative comparison showing an outlier that would dominate a treemap". Include 4 key insight callouts with small icons: 1) headline number "57" with short interpretation "Largest block candidate, far above the cluster" and a spotlight icon, 2) headline number "+33" with short interpretation "Outlier exceeds the next highest category by 33 units" and a warning icon, 3) headline number "20–24" with short interpretation "Most categories sit in a tight mid-range" and a cluster icon, 4) headline number "2.5x" with short interpretation "Outlier is about two and a half times a typical category" and a scale icon. Add a small side annotation in English near the tallest bar: "Surprise outlier". Add a compact legend or note in English: "Illustrative values for demonstration". Add a small source / data-note strip at the bottom in English: "Data note: Illustrative example only. Figures are not sourced and are shown for visual explanation." Ensure no misleading axis truncation or scale manipulation. Visual style: retro 1970s magazine charts, editorial blue & cream palette, slightly textured paper background, vintage print feel, geometric iconography, bold editorial typography, understated cream canvas, navy and slate blue bars with warm cream and muted teal accents, surprise / outlier storytelling 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.
