Marimekko graph style Sankey infographic pipeline example

Data visualization infographic titled "Choropleth Map Example" using a SANKEY FLOW as the dominant visual element to show progress through a pipeline. Main graphic: a large left-to-right Sankey flow with clear stages labeled in English: "Potential Regions" -> "Data Collected" -> "Mapped Correctly" -> "High Priority" -> "Action Completed". Use realistic plausible illustrative values with widths proportional to flow: 120 regions at start, 96 data collected, 78 mapped correctly, 42 high priority, 31 action completed, with smaller branch losses labeled "Missing data" 24, "Validation errors" 18, "Lower priority" 36, "Pending action" 11. Include sharp English axis-style guides and tick marks along the horizontal pipeline progression labeled "Stage 1", "Stage 2", "Stage 3", "Stage 4", "Stage 5" and a vertical reference scale labeled "Regions" with clean ticks at 0, 20, 40, 60, 80, 100, 120; no truncated or misleading scale. Secondary supporting visual: a small inset choropleth map example panel in the corner, clearly labeled "Illustrative choropleth inset", showing simplified regions shaded from red to green to connect the topic to map-based output. Add 4 key insight callouts with headline number, short interpretation in English, and small icon: "80%" "Most regions reached the data collection stage" with clipboard icon; "65%" "Nearly two-thirds were mapped correctly after validation" with map pin icon; "35%" "About one-third became high-priority regions" with alert triangle icon; "26%" "Roughly one-quarter completed the full pipeline" with checkmark icon. Add hand-drawn annotation arrows and circled notes emphasizing where the biggest drop-offs happen, especially between "Mapped Correctly" and "High Priority". Visual style: hand-annotated sketchnote, editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout; textured marker lines, sketch arrows, neat handwritten-style annotations while keeping chart geometry precise and legible. Color palette: high-contrast red & green, with losses in red tones, successful progression in green tones, black ink outlines, off-white paper background, strong contrast, energetic analytical mood. Include concise legend in English: "Progress", "Drop-off", "Illustrative regions". Add a small bottom strip labeled "SOURCE / DATA NOTE" with text: "Illustrative example. Figures are illustrative and created for visualization mockup purposes only." 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.
