Diagramm Design für Sankey-Infografik zur Choroplethenkarte

Data visualization infographic titled "Choropleth Map Example" using SANKEY FLOW as the dominant visual element to show progress through a pipeline. Create a large, central sankey diagram with clear left-to-right stages labeled in English: "Data Collection", "Geocoding", "Regional Aggregation", "Map Classification", "Published Choropleth". Use realistic plausible illustrative values flowing through the stages, for example 1,200 records entering, 1,050 geocoded, 920 validated by region, 780 classified, 720 published. Show branch losses as smaller side flows labeled "Missing location", "Invalid boundaries", "Unclassified values". Include sharp axis labels and tick marks in English where applicable, such as a horizontal progress scale labeled "Pipeline stage" and a subtle quantitative reference scale labeled "Records (illustrative)" with clear tick marks, no misleading truncation. Add a small secondary inset thumbnail of a choropleth map example in monochrome ink tones, labeled in English "Example choropleth output", with 4 legend bins: "Very low", "Low", "Medium", "High". Add 4 key insight callouts with small icons, each in English: 1) headline number "1,200" with note "Initial records collected" and database icon, 2) headline number "88%" with note "Successfully geocoded before mapping" and pin icon, 3) headline number "720" with note "Final mapped regions published" and map icon, 4) headline number "40%" with note "Largest drop occurs during classification cleanup" and warning icon. Add a compact SOURCE / DATA-NOTE strip in English at the bottom reading exactly: "Source / Data note: Illustrative example. Figures are illustrative unless sourced by the user." Visual style: editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout, monochrome ink palette with black, charcoal, slate gray, warm off-white background, restrained contrast, precise linework, elegant newsroom presentation, analytical and trustworthy mood. Ensure crisp English labels, legends, captions, metric names, stage names, and annotation text throughout. 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.
