Bad Data Visualization Examples: Funnel Bubble Chart Infographic

Data visualization infographic titled "Funnel Chart Conversion" using a BUBBLE CHART as the dominant visual element: a 3D-style scatter / bubble comparison that contrasts strong vs weak conversion funnels across sequential stages. Show a clean x-axis labeled "Funnel Stage" with evenly spaced categories "Awareness", "Visit", "Sign-up", "Trial", "Purchase" and a y-axis labeled "Conversion Rate (%)" from 0 to 100 with sharp tick marks at 0, 20, 40, 60, 80, 100; no truncated axis, no misleading scaling. Use bubble size to represent stage volume, with two clearly contrasted bubble series and legend labels "High-performing funnel" and "Low-performing funnel". Use realistic illustrative figures only, clearly marked as illustrative: high-performing funnel bubbles around 100%, 62%, 34%, 19%, 11%; low-performing funnel bubbles around 100%, 38%, 14%, 6%, 2%, with bubble sizes decreasing by stage. Add subtle 3D depth shading to bubbles but keep the layout editorial and readable, emphasizing the contrast between the two trajectories.

Include 4 key insight callouts placed around the chart, each with a small icon, a headline number, and a short interpretation in English: 1) "11%" — "Strong funnel retains buyers through the final stage" with an upward arrow icon; 2) "2%" — "Weak funnel leaks most prospects before purchase" with a warning triangle icon; 3) "24 pts" — "Largest gap appears by the Sign-up stage" with a split comparison icon; 4) "5.5x" — "Final conversion is dramatically higher in the stronger path" with a target icon.

Add a compact side note or footer strip labeled "Source / Data note" with the exact text: "Illustrative example. Figures are plausible sample values for visual demonstration and are not sourced data." Include a tiny legend note: "Bubble size = remaining audience volume".

Visual style: retro 1970s magazine charts, editorial blue & cream palette, muted navy, denim blue, slate, warm cream, faded paper background, subtle print texture, thin black ink outlines, geometric icons, nostalgic editorial typography, balanced negative space, high-contrast labels for readability. Mood: analytical yet playful, intentionally showing contrast in a polished magazine-infographic manner. Composition should feel like a cautionary editorial example of funnel-chart storytelling while still being technically clear and accurate. 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.
