Flourish sankey style funnel chart conversion infographic

Data visualization infographic titled "Funnel Chart Conversion" using a BUBBLE CHART as the dominant visual element, styled as a 3D scatter that reveals inequality across funnel stages. Show a clean editorial layout with one large main chart centered. X-axis label in English: "Funnel stage" with evenly spaced stage categories "Visits", "Product Views", "Add to Cart", "Checkout", "Purchase". Y-axis label in English: "Conversion rate (%)" with full scale from 0 to 100, clear tick marks at 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, no truncation. Bubble size encodes absolute users, legend in English: "Bubble size = users". Add subtle depth/shadow to bubbles for 3D scatter feel, but keep chart mathematically readable and not distorted. Use realistic illustrative figures clearly marked as illustrative: Visits 100000 users at 100%, Product Views 42000 users at 42%, Add to Cart 11500 users at 11.5%, Checkout 4700 users at 4.7%, Purchase 1800 users at 1.8%. Emphasize the steep inequality between top-of-funnel volume and final conversion with descending bubble sizes and positions. Add a small secondary annotation or guide line labeled in English: "Illustrative funnel decline".

Include 4 insight callouts around the chart, each with a small icon, a bold headline number, and a short interpretation in English: 1) icon of warning triangle, headline "98.2%", text "Illustrative drop-off from first visit to purchase"; 2) icon of eye, headline "42%", text "Illustrative share of visitors who reach product views"; 3) icon of cart, headline "11.5%", text "Intent concentrates sharply before checkout"; 4) icon of receipt or checkmark, headline "1.8%", text "Final purchase conversion is highly unequal versus entry traffic". Optionally add a fifth mini-callout with a stacked dots icon: headline "55x", text "Visits outnumber purchases by roughly fifty-five to one".

Add a compact source strip at the bottom in English: "Data note: Illustrative example for visual explanation only. Figures are not sourced and should not be treated as observed market data." Add a tiny methodology note in English: "Axes use full scale; no truncation or misleading scale manipulation." Do not cite any fake organization or publication as source.

Visual style: editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. Monochrome ink palette only: black, charcoal, warm gray, off-white, subtle ink washes; use contrast through tone and line weight rather than color. Mood: analytical, precise, understated, high-trust newsroom graphic. Use crisp typography, sharp axis labels and tick marks, thin gridlines, elegant legend, restrained annotations, lots of white space, print-quality composition. Keep all labels, captions, legends, metric names, and notes in exact English render-ready text.

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.
