Vega Vega Lite Radar Spider Chart Comparison Infographic

Data visualization infographic titled "Radar Spider Chart" using COMPARISON COLUMNS as the dominant visual element to clearly show contrast between categories, avoiding radar geometry for more accurate comparison. Main chart: a large side-by-side comparison column chart with 6 categories on the x-axis labeled exactly "Speed", "Accuracy", "Scalability", "Usability", "Flexibility", "Cost Efficiency" and a y-axis labeled exactly "Score (0–100)" with sharp tick marks at 0, 20, 40, 60, 80, 100, no truncated axis, clean gridlines, and two contrasting series in the legend labeled exactly "Option A" and "Option B". Use realistic illustrative values: Option A = 82, 74, 91, 68, 79, 61; Option B = 58, 88, 67, 84, 72, 77. Add 4 key insight callouts around the chart, each with a small icon: 1) headline number "24-point gap" with interpretation "Option A leads strongly on Scalability" and a scaling icon; 2) headline number "20-point gap" with interpretation "Option B outperforms on Usability" and a cursor icon; 3) headline number "16-point gap" with interpretation "Speed advantage favors Option A" and a lightning icon; 4) headline number "14-point gap" with interpretation "Accuracy is stronger for Option B" and a target icon. Include a small secondary mini-panel labeled exactly "Contrast Summary" with compact horizontal bars showing category-by-category gaps. Add a small source / data-note strip at the bottom labeled exactly "Data note: Illustrative example. Values are sample scores for visual demonstration only." Visual style: dark dashboard, FT pink and navy palette, charcoal background, deep navy panels, FT pink highlights, muted gray gridlines, crisp white and soft gray typography, subtle glow accents, high contrast, analytical and modern mood. Include the phrase "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.
