Sankeymatic Pie vs Donut Chart Trend Infographic

Data visualization infographic titled "Pie Chart vs Donut Chart" using a SANKEY FLOW as the dominant visual element to show the trend in chart preference over time. Design a left-to-right pipeline with clearly labeled time stages in English: "2010", "2015", "2020", "2025". Show flows splitting between two destination categories: "Pie Chart" and "Donut Chart". Use realistic plausible illustrative values, with trend emphasis: in 2010 total 100 illustrative uses split into 68 for Pie Chart and 32 for Donut Chart; in 2015 split 58 and 42; in 2020 split 46 and 54; in 2025 split 39 and 61. Make the Sankey ribbons thick, readable, and dominant, with clean node blocks and subtle directional progression. Include a compact baseline scale and small tick references beneath the flow for counts, with sharp axis labels and tick marks in English, no truncation or misleading scaling. Add a small side mini-legend in English with exact labels: "Pie Chart", "Donut Chart", "Illustrative share of usage". Add 4 key insight callouts around the chart, each with a small icon, headline number, and short interpretation in English: "61%" + "Donut leads in 2025" with a ring icon; "22 pts" + "Pie drops since 2010" with a downward arrow icon; "2020" + "Donut overtakes pie" with a crossover icon; "100" + "Illustrative examples per period" with a dataset icon. Add a small source/data-note strip at the bottom in English reading exactly: "Data note: Illustrative example only. Figures are not sourced and are shown for visual explanation." Visual style: retro 1970s magazine charts, editorial blue & cream palette with muted navy, dusty teal, warm cream, faded ink blue, and subtle paper texture; nostalgic print-era typography; geometric iconography; balanced editorial layout. Include search-intent-inspired visual cues only, not on-image text, evoking flow-diagram construction aesthetics. Use 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.
