Interesting Datasets for Visualization Donut Infographic

Data visualization infographic titled "Bubble Chart Example" using PIE / DONUT (composition) as the dominant visual element to show contrast between two main groups and their subcomponents. Create a large central donut chart with sharp English labels, clean percentage markers, clear segment boundaries, and precise tick-style radial guides around the ring. Use realistic illustrative values: Group A = 68%, Group B = 32%. Split Group A into "Consumer Apps" 28%, "Climate Data" 22%, "Urban Mobility" 18%. Split Group B into "Health Research" 14%, "Finance" 10%, "Education" 8%. Emphasize contrast with strong visual separation and annotation arrows. Include a small secondary mini-bubble-chart sketch panel as a supporting visual cue only, labeled "Bubble chart example" and "Size = value", but keep the donut chart dominant.

Add 4 key insight callouts around the chart, each with a headline number, short interpretation in English, and a small icon: 1) "68%" — "Most examples cluster in practical, everyday topics" with a small apps icon. 2) "32%" — "Specialist datasets form a smaller but distinct share" with a small lab icon. 3) "14 pts" — "The largest contrast is between Consumer Apps and Health Research" with a small compare-arrows icon. 4) "50%" — "The top two segments make up half of all illustrative examples" with a small pie-slice icon.

All labels, legends, and captions must be in English, including exact on-image text such as: "Bubble Chart Example", "Composition of Interesting Datasets for Visualization", "Consumer Apps", "Climate Data", "Urban Mobility", "Health Research", "Finance", "Education", "Share of examples (%)", "Illustrative example", "Contrast between broad-interest and specialist topics", "Larger share", "Smaller share", and "Size = value". Ensure axis-like guides and tick marks are visible and not misleading; no truncation or scale manipulation.

Style: hand-annotated sketchnote with marker strokes, scribble circles, underlines, sticky-note callouts, and informal editorial annotations while preserving precise chart geometry. Palette: high-contrast red & green with off-white paper background, black ink outlines, subtle gray guide marks. Mood: analytical, lively, editorial, contrast-driven. Include editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout.

Add a small bottom SOURCE / DATA-NOTE strip in English reading: "DATA NOTE: Figures are illustrative example values for layout demonstration only." and "No external source provided." 

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.
