Dark Inequality Donut Infographic with mosaic plot in r

Data visualization infographic titled "Bubble Chart Example" using a PIE / DONUT (composition) as the dominant visual element to show inequality. Create a large central donut chart with sharp English labels, clear segment annotations, crisp legend, and clean percentage markers around the ring. Use realistic plausible illustrative values that emphasize imbalance: segment 1 "Top Group" = 62%, segment 2 "Upper Middle" = 21%, segment 3 "Lower Middle" = 11%, segment 4 "Bottom Group" = 6%. Include a thin outer comparison ring or small side mini-bars to reinforce concentration without misleading scale manipulation. All labels, legends, captions, and numeric markers must be in English with sharp tick styling and precise typography. Even though this is a composition chart, include a small supporting scale guide with evenly spaced tick marks labeled "0%", "25%", "50%", "75%", "100%" in English to satisfy dashboard readability.

Add 4 key insight callouts around the chart, each with a headline number, short interpretation in English, and a small icon: 1) "62%" — "Top segment holds nearly two-thirds of the total" with crown icon. 2) "6%" — "Bottom group captures only a small share" with downward arrow icon. 3) "10x" — "Top vs bottom share differs by about tenfold" with scale balance icon. 4) "83%" — "Top two groups combined dominate the composition" with stacked layers icon. Mark all figures as illustrative.

Include a compact side panel titled "How to Read This" in English with two short bullets: "Large slices indicate larger shares" and "Illustrative example showing unequal composition". Add a subtle small footer strip in English reading "Data note: Illustrative example. Values are placeholders for visualization only, not sourced statistics." and "Source: Illustrative example".

Visual style: dark dashboard, high-contrast editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. Palette: deep navy background, FT pink primary highlight, soft blush pink secondary slices, muted slate blue support tones, thin white grid accents, elegant off-white typography. Mood: analytical, premium, financial-newsroom, inequality-focused, polished and modern. Use balanced spacing, crisp vector edges, subtle glow on highlighted segment, and no decorative clutter. 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.
