ggplot interactive Choropleth Map Progress Infographic

Data visualization infographic titled "Choropleth Map Example" using a CHOROPLETH MAP as the dominant visual element: a regional map shaded from light cream to deep editorial blue to show progress across regions, with a clear English legend labeled "Progress Index (%)" and evenly spaced tick marks at "0", "20", "40", "60", "80", "100". Show distinct regions with crisp borders and readable English region labels such as "North", "South", "East", "West", "Central", "Northeast", "Northwest", "Southeast", "Southwest". Include a small secondary comparison strip or mini ranking beside the map to reinforce highest-to-lowest regional progress, but keep the choropleth map dominant. Use realistic illustrative values with visible labels, for example: "North 82%", "West 76%", "Central 68%", "East 61%", "South 49%", "Northeast 73%", "Northwest 57%", "Southeast 64%", "Southwest 53%". Emphasize storytelling angle: progress improving across regions, with visual hierarchy that highlights top-performing and catching-up regions. Add 4 key insight callouts placed around the map, each with a headline number, short interpretation in English, and a small icon: "82%" with "Highest progress in the North" and an upward arrow icon; "49%" with "South remains the lowest but improving" and a small seedling icon; "+33 pts" with "Gap between top and bottom regions" and a split-bars icon; "5 of 9" with "Majority of regions are above 60%" and a checkmark icon. Include sharp labels, legend text, captions, and any scale text all in English. Add a small bottom strip labeled "Data note" with the text "Illustrative example. Figures are illustrative and not based on sourced data." Include subtle annotation text such as "Regional progress overview" and "Darker color indicates higher progress". Visual style: retro 1970s magazine charts, editorial blue & cream palette, slightly muted ink textures, warm paper background, vintage publication feel, geometric icons, bold serif headline paired with clean sans-serif labels. Overall mood: optimistic, analytical, polished. 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.
