Hierarchy Design Online Sankey Pipeline Bubble Chart Example

Data visualization infographic titled "Bubble Chart Example" using SANKEY FLOW as the dominant visual element to show progress through a pipeline. Create a Reuters / Economist editorial-style dark mode neon infographic with FT / Bloomberg-grade chart aesthetics, editorial data journalism illustration, vector-clean infographic layout. Main chart: a left-to-right Sankey pipeline with clearly labeled stages in English, showing plausible illustrative progression values and flow widths: "Awareness" 12,000 -> "Visits" 8,400 -> "Sign-ups" 4,900 -> "Qualified" 2,800 -> "Customers" 1,350 -> "Repeat Customers" 620. Include subtle baseline guides, sharp labels, value annotations, and neat tick references for volume scale in English such as "0", "2,000", "4,000", "6,000", "8,000", "10,000", "12,000". Add small secondary comparison bubbles near each stage as a supporting motif to reference the topic "bubble chart example", with bubble sizes matching stage totals and labeled "Illustrative volume". Show visible drop-off branches in the Sankey, for example from "Visits" to "Bounced" 3,600, from "Sign-ups" to "Inactive" 2,100, from "Qualified" to "Unconverted" 1,450, all marked as illustrative. Include 4 key insight callouts with small icons: 1) headline number "70%" with short interpretation "Awareness to Visits conversion remains strong" and an upward arrow icon; 2) headline number "1,350" with short interpretation "Customers reached after steady mid-funnel filtering" and a target icon; 3) headline number "54%" with short interpretation "Largest drop occurs between Visits and Sign-ups" and a warning triangle icon; 4) headline number "620" with short interpretation "Repeat customer base shows retained value" and a loop/refresh icon. Add compact chart labels and legends in exact English, including "Pipeline Stage", "Volume", "Drop-off", "Retained Flow", "Illustrative example". Use a dark charcoal to near-black background, neon cyan, electric blue, magenta, violet, and lime accents with restrained glow, high contrast typography, thin crisp gridlines, and sophisticated newsroom presentation. Include a small bottom strip reading "SOURCE / DATA NOTE: Illustrative example. Figures are illustrative unless sourced data is provided." Keep layout balanced, analytical, and uncluttered, with no misleading axis truncation or scale manipulation. 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.
