Seaborn Plotly Sankey Pipeline Infographic Example

Data visualization infographic titled "Bubble Chart Example" using SANKEY FLOW as the dominant visual element to show progress through a pipeline. Create a large, central Sankey diagram with clean left-to-right flow stages labeled in English: "Raw Data", "Filtered Data", "Categorized", "Visualized", "Published". Use realistic plausible illustrative values with clearly labeled node totals and flow widths, for example 1,200 -> 920 -> 640 -> 410 -> 320, with branch losses labeled "Dropped", "Merged", and "Reworked". Include sharp axis-like alignment guides, tick marks, and numeric scale references in English to reinforce quantitative readability, with no misleading truncation or scale manipulation. Add 4 key insight callouts around the chart, each with a small icon, a headline number, and a short interpretation in English: "73%" "Retained after filtering" with funnel icon; "410" "Reached visualization stage" with chart icon; "320" "Final outputs published" with check icon; "880" "Total reductions across all steps" with arrow-down icon. Add a small top or side contextual label noting "Illustrative workflow progression". Include a compact source / data-note strip at the bottom in English reading: "Data note: Illustrative example. Figures are plausible sample values, not sourced real-world data." Visual style: editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout, monochrome ink palette with black, charcoal, slate gray, soft off-white background, subtle line-weight hierarchy, crisp typography, restrained newsroom mood, analytical and polished. Ensure all chart labels, legends, captions, node names, callouts, and metric names are sharp and readable in English. 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.
