Visualisation de donnees infographic en donut analytique

Data visualization infographic titled "Line Chart Best Practices" using a PIE / DONUT (composition) chart as the dominant visual element to show inequality in what makes an effective line chart. Create a large central donut chart with clearly separated segments and crisp English labels, legend, percentages, and value annotations. Use realistic plausible illustrative shares such as: "Clear trend emphasis" 38%, "Accurate axis scaling" 24%, "Readable labels" 16%, "Appropriate time intervals" 12%, "Context and annotations" 7%, "Decorative styling" 3%. Make the inequality visually obvious, with the largest 2 segments dominating and the smallest decorative segment tiny. Even though this is a donut chart, include sharp supporting label rules, precise percentage markers, and clean annotation lines; do not imply any misleading axis truncation or manipulated scale anywhere in the design.

Add 4 key insight callouts around the chart, each with a small icon, a headline number, and a short interpretation in English: 1) icon of trending line, headline "62%", text "Most chart quality comes from trend clarity and honest scaling." 2) icon of ruler / axis, headline "24%", text "Axis choices strongly affect how viewers judge change." 3) icon of text label, headline "16%", text "Readable labels improve comprehension more than extra decoration." 4) icon of sparkles / paintbrush, headline "3%", text "Visual flair contributes least to effective line charts." Mark all figures as illustrative.

Include a compact side legend and micro-explainer labels in English only, with exact rendered text such as "Composition of effective line chart design", "Illustrative share of impact", "Percent of overall effectiveness", and segment labels exactly as written above. Add a small SOURCE / DATA-NOTE strip at the bottom with the exact text: "Data note: Illustrative example for infographic storytelling. Figures are not from a sourced dataset." 

Visual style: minimal flat design, rainbow categorical palette, clean white or very light neutral background, subtle editorial spacing, geometric icons, balanced negative space, high contrast typography, modern sans-serif font, sharp vector edges, restrained shadows or none. Overall mood: analytical, clear, instructive, elegant. Compose as 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.
