Color Combination Chart for Graphic Design Data Infographic

Data visualization infographic titled "Sankey Diagram Example" using COMPARISON COLUMNS as the dominant chart. Create a dark dashboard editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. Theme and mood: sleek, analytical, high-contrast, premium newsroom graphics. Color palette: deep navy background, FT pink primary bars, muted pink secondary accents, soft gray gridlines, white and pale blue text, subtle glow highlights.

Main visual: a large comparison column chart centered on the canvas with sharp axis labels and tick marks in English. X-axis label: "Flow Category". Y-axis label: "Volume (units)". Use 6 vertical columns with realistic illustrative values: "Direct Transfer" 42, "Processing" 55, "Distribution" 61, "Returns" 18, "Loss / Leakage" 79, "Final Delivery" 47. Make "Loss / Leakage" the clear surprise outlier with the tallest FT pink column, while the other columns are navy-pink variations. Show full zero baseline, evenly spaced tick marks from 0 to 80 at increments of 10, no axis truncation or misleading scaling. Add subtle numeric labels above each bar with the word "illustrative" in small type.

Support storytelling angle: emphasize the outlier. Add a faint mini-side annotation reading "Unexpected spike" next to "Loss / Leakage" and a thin highlight ring or glow around that column. Include a small secondary reference band or average marker line across the bars labeled "Average = 50".

Add 4 key insight callouts around the chart, each with a small icon, headline number, and short interpretation in English:
1. Icon: warning triangle. Headline: "79". Text: "Loss / Leakage stands far above the average, making it the standout outlier." 
2. Icon: bar chart. Headline: "61". Text: "Distribution is the strongest non-outlier stage, but still well below the peak." 
3. Icon: downward arrow. Headline: "18". Text: "Returns is the smallest category, suggesting a narrow reverse flow." 
4. Icon: compare arrows. Headline: "+29". Text: "The outlier exceeds the average by 29 units, creating the main visual surprise." 

Add a compact legend in English with color swatches: "Typical categories", "Outlier highlight", "Average line".

Add a small bottom strip labeled "Source / Data note" with the exact text: "Illustrative example. Figures are illustrative and not sourced from an external dataset." Keep it clearly separated, subtle, and readable.

Ensure all headings, labels, captions, legends, and metric names are written exactly in English, including: "Sankey Diagram Example", "Flow Category", "Volume (units)", "Direct Transfer", "Processing", "Distribution", "Returns", "Loss / Leakage", "Final Delivery", "Average = 50", "Illustrative example", "Source / Data note".

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.
