Visualisation de donnees : infographie sankey en dashboard

Data visualization infographic titled "Line Chart Best Practices" using a SANKEY FLOW as the dominant visual element to show progress through a best-practice pipeline. Create a dark dashboard composition with FT pink and navy palette: deep navy background, Financial Times pink highlights, soft coral accents, muted blue-gray secondary links, crisp white typography, subtle gridlines. Editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout.

Main visual: a large left-to-right sankey flow / pipeline with sharp labels, node titles, flow values, guide rails, and small numeric markers in English. Structure the pipeline as five stages with realistic illustrative values: "Raw Data" 100%, flowing into "Clean Time Series" 92%, then splitting to "Consistent Scale" 78%, "Clear Labels" 74%, "Meaningful Highlights" 61%, and culminating in "Reader Understanding" 84 score. Include visible flow widths proportional to values and small stage annotations. Add a slim bottom baseline with clear tick marks labeled in English as process steps: "Collect", "Clean", "Scale", "Label", "Annotate", "Interpret". Add a side mini-checklist panel with concise English labels: "Start at zero when needed", "Keep time intervals regular", "Avoid clutter", "Label directly", "Highlight the message".

Ensure the sankey is the hero chart, but include dashboard-style measurement cues and precise English metric labels such as "Illustrative completion rate (%)", "Clarity score", and "Stage retention". No misleading scale tricks, no exaggerated flow distortions beyond standard sankey proportionality.

Add 4 key insight callouts around the chart, each with a headline number, short interpretation in English, and a small icon:
1. "92%" — "Clean, ordered data is the first major quality gain" — icon: database/check.
2. "78%" — "Consistent scales prevent visual misreading" — icon: axis/ruler.
3. "61%" — "Annotations are where many charts lose storytelling power" — icon: pen/highlighter.
4. "84" — "Direct labels and highlights improve reader understanding" — icon: eye/lightbulb.

Add a compact source / data-note strip at the bottom in English: "Data note: Illustrative example for infographic design. Figures are illustrative unless sourced by the user." Add a small caution note in English: "No axis truncation or scale manipulation." 

Visual mood: analytical, modern, newsroom-grade, high contrast, polished dashboard UI, elegant negative space, thin divider lines, subtle glow on pink links, clean legends. All text visible in the image must be English labels only, even though the search intent is French and should not appear on-image.

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.
