Data Studio Geo Map Donut Infographic with Sankey Example

Data visualization infographic titled "Sankey Diagram Example" using a PIE / DONUT (composition) chart as the dominant visual element to show contrast between two clearly different shares. Main chart: a large donut chart with two major segments and two minor segments, clean vector geometry, sharp outer labels, crisp leader lines, precise percentage labels, and subtle radial tick guides in English. Use realistic plausible illustrative values: Segment A "High Flow" 58%, Segment B "Low Flow" 32%, Segment C "Other" 7%, Segment D "Loss" 3%. Emphasize the contrast between the two dominant categories with strong visual separation and annotation. Include a small side mini-diagram as a secondary sketch reference showing simplified left-to-right flow ribbons labeled "Input", "Processed", "Output", "Loss" to visually hint at what a Sankey diagram is, but keep the donut chart as the primary chart archetype. Add 4 key insight callouts with hand-drawn note styling, each containing a headline number, a short interpretation in English, and a small icon: "58%" "Largest share dominates the composition" with arrow icon; "26 pts" "Gap between the top two segments shows strong contrast" with split-circle icon; "10%" "Minor categories remain limited in total" with small pie icon; "3%" "Loss is minimal in this illustrative example" with warning-drop icon. Add a compact legend in English: "High Flow", "Low Flow", "Other", "Loss". Add a small source / data-note strip at the bottom in English: "Data note: Illustrative example. Figures are plausible mock values for demonstration only, not sourced data." Ensure no misleading scale manipulation and keep proportions accurate. Visual style: hand-annotated sketchnote, high-contrast red & green palette with black ink outlines, off-white paper texture, energetic newsroom markup, editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. Overall mood: analytical, contrasting, vivid, explanatory. 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.
