Kieran Healy Data Visualization Sankey Portfolio Infographic

Data visualization infographic titled "Tree Map Example" using a SANKEY FLOW as the dominant visual element, designed to show trend-like movement through a pipeline from left to right across 5 stages. Create a large, central sankey diagram with clear node blocks and flowing bands, plus a subtle horizontal time/progression axis beneath it with sharp English tick marks labeled "Stage 1", "Stage 2", "Stage 3", "Stage 4", "Stage 5". Structure the flow as a hierarchical category example inspired by treemap logic: "Total Portfolio" splits into "Technology", "Consumer", "Industrial", "Healthcare", then progressively reallocates over stages to show changing composition. Use realistic plausible illustrative values: Stage 1 total 100, with Technology 32, Consumer 24, Industrial 22, Healthcare 22; Stage 3 totals: Technology 38, Consumer 21, Industrial 19, Healthcare 22; Stage 5 totals: Technology 44, Consumer 18, Industrial 16, Healthcare 22. Show internal sub-flows where useful, such as "Software", "Semiconductors", "Retail", "Food", "Machinery", "Logistics", "Pharma", "Services". Ensure band widths accurately reflect values with no misleading scale manipulation. Include crisp English labels directly on nodes and along major bands: "Total Portfolio", "Technology", "Consumer", "Industrial", "Healthcare", "Software", "Semiconductors", "Retail", "Food", "Machinery", "Logistics", "Pharma", "Services". Add sharp axis labels and tick marks in English only, with a small vertical reference scale labeled "Share of Total (%)" and ticks at 0, 10, 20, 30, 40, 50. Add 4 key insight callouts with a headline number, short interpretation in English, and a small icon: "44%" + "Technology becomes the largest share by the final stage" + upward arrow icon; "-6 pts" + "Consumer contracts steadily across the pipeline" + shopping bag icon; "-6 pts" + "Industrial loses weight as flows narrow over time" + factory icon; "22%" + "Healthcare remains broadly stable throughout" + medical cross icon. Add a small source / data-note strip at the bottom in English: "Data note: Illustrative example for layout and storytelling. Values are not sourced and are shown for demonstration only." Specify Reuters / Economist editorial style, dark mode neon palette with charcoal-black background, electric cyan, lime, magenta, amber, and violet accents, restrained glow, high contrast text, precise grid, elegant spacing, analytical newsroom mood. 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.
