Bubble Chart Funnel Conversion Trend Infographic

Data visualization infographic titled "Funnel Chart Conversion" featuring a TREND LINE (over time) as the dominant visual element, because the storytelling angle is to show the trend. Show monthly funnel conversion rate across 12 periods with a sharp, clearly labeled x-axis "Month" and y-axis "Conversion Rate (%)" with honest full-scale tick marks from 0% to 100%, no truncation or misleading scaling. Plot a bold high-contrast line with annotated points using realistic illustrative values such as 42%, 45%, 44%, 48%, 51%, 49%, 54%, 57%, 55%, 60%, 63%, 66%, and add a faint secondary contextual layer of ranked horizontal bars for funnel stages labeled "Visits", "Sign-ups", "Qualified Leads", "Trials", "Purchases" with plausible illustrative counts and stage conversion percentages, making the trend line clearly dominant. Include 4 key insight callouts with small icons: "66%" — "Peak conversion at period end" with upward arrow icon; "+24 pts" — "Net improvement from start to finish" with growth icon; "57%" — "Midyear acceleration after optimization" with spark icon; "5 stages" — "Largest drop occurs between 'Visits' and 'Sign-ups'" with funnel icon. Add concise annotation notes in a hand-drawn sketchnote style pointing to inflection points, labeled exactly "Steady improvement", "Temporary dip", "Recovery", "Best month". Include a small source / data-note strip reading exactly "Data note: Illustrative example. Figures are illustrative and not sourced unless provided by the user." Visual style: hand-annotated sketchnote, high-contrast red & green palette, editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout, textured marker strokes, neat handwritten annotation accents, clean white background, strong hierarchy, crisp labels, compact legend, analytical but lively mood. 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.
