Power BI Map Visuals Infographic with Choropleth Trend Map

Data visualization infographic titled "Pie Chart vs Donut" using CHOROPLETH MAP as the dominant visual element to compare regional trend patterns over time. Show a large choropleth map divided into clear regions with monochrome ink intensity encoding values, plus a compact secondary time-trend strip or mini trend lines beside the map to support the storytelling angle "show the trend" while keeping the map dominant. Use sharp English labels, legends, scale ticks, region names, and year markers. Include a clear legend labeled "Illustrative trend index" with a full non-truncated scale from 0 to 100, tick marks at 0, 20, 40, 60, 80, 100. Add small regional labels in English such as "North", "South", "East", "West", "Central". Use realistic illustrative values: North 72, South 58, East 64, West 49, Central 67 for latest period; mini trend values over 2020, 2021, 2022, 2023, 2024 showing gradual change. Add 4 key insight callouts with small icons: "72" + "North leads the illustrative index" + upward arrow icon; "49" + "West remains the lowest region" + map pin icon; "23 pts" + "Gap between highest and lowest regions" + compare icon; "2020-2024" + "Overall trend shows steady regional shift" + trend line icon. Include a small comparison note panel explaining the topic with concise editorial wording in English: "Pie charts emphasize shares" and "Donut charts add center space for a headline metric". Add a small SOURCE / DATA-NOTE strip reading "Data note: Illustrative example only. Figures shown are not sourced unless provided by the user." Visual style: editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout, monochrome ink palette with off-white background, charcoal, black, slate gray, and subtle ink wash shading, precise newsroom layout, analytical and restrained mood, crisp typography, balanced whitespace, no decorative clutter, no misleading scale manipulation. 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.
