Marimekko Graph Style Donut Chart Infographic Example

Data visualization infographic titled "Choropleth Map Example" using a PIE / DONUT (composition) chart as the dominant visual element to show contrast. Large central donut chart with sharp English labels, clean segment dividers, clear percentage annotations, and a thin outer ring for category emphasis. Include a small secondary inset world or regional choropleth-style mini-map as a contextual example only, but keep the donut chart dominant. Use realistic illustrative values that contrast clearly: "High intensity" 42%, "Medium intensity" 28%, "Low intensity" 18%, "Minimal coverage" 12%. Add crisp English chart labeling such as "Share of mapped areas", "Percentage", and clear tick marks where applicable on any supporting scale or legend. 

Add 4 key insight callouts around the chart, each with a small icon: 1) "42%" with short interpretation "Largest share falls in high intensity zones" and a map-pin icon. 2) "14 pts" with short interpretation "High intensity exceeds medium intensity by a wide margin" and a contrast icon. 3) "30%" with short interpretation "Low and minimal areas together remain a minority" and a split-circle icon. 4) "70%" with short interpretation "Most mapped areas cluster in medium-to-high categories" and a layers icon. 

Include a compact legend in English with exact labels: "High intensity", "Medium intensity", "Low intensity", "Minimal coverage". Add a small SOURCE / DATA-NOTE strip reading exactly: "Data note: Illustrative example only. Figures are not sourced real-world statistics." 

Visual style: minimal flat design, rainbow categorical palette, strong contrast between segments, white or very light neutral background, editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. Mood: analytical, contemporary, clear, high-contrast, comparison-focused. Ensure no misleading scale manipulation, no fake authoritative sources, no watermarks. Include subtle layout cues that visually evoke search intent for a marimekko graph without naming it on-image. 

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.
