Radar Spider Chart Infographic to Visualize Missing Values in Python

Data visualization infographic titled "Radar Spider Chart" using COMPARISON COLUMNS as the dominant visual element to show the breakdown of components typically visualized in a radar spider chart context, reinterpreted clearly as grouped vertical columns. Main chart: a large comparison column chart with 5 categories on the x-axis labeled "Completeness", "Consistency", "Accuracy", "Uniqueness", and "Validity"; y-axis labeled "Share of records (%)" from 0 to 100 with clear tick marks at 0, 20, 40, 60, 80, 100; two series in a clean legend labeled "Observed values" and "Missing values". Use realistic illustrative values: Completeness 82 observed / 18 missing, Consistency 74 / 26, Accuracy 91 / 9, Uniqueness 68 / 32, Validity 87 / 13. Add subtle value labels above each bar pair with the word "illustrative" in small text. Include 4 key insight callouts around the chart, each with a small icon: 1) headline number "32%" with interpretation "Highest missing share appears in Uniqueness" and a warning icon; 2) headline number "91%" with interpretation "Accuracy shows the strongest observed-value rate" and a check icon; 3) headline number "18.0%" with interpretation "Average missing rate across dimensions remains moderate" and a calculator icon; 4) headline number "23 pts" with interpretation "Gap between best and weakest category is substantial" and a compare icon. Add a small side annotation panel titled "How to read this breakdown" with concise labels explaining that comparison columns make category differences easier to compare than a spider layout. Include a bottom strip labeled "Source / Data note" with text "Illustrative example. Figures are illustrative and not from a cited external dataset unless user-supplied." Ensure no misleading axis truncation or scale manipulation; axis starts at zero. Visual style: NYT graphics desk, Economist warm beige palette, soft parchment background, warm beige, muted brick red, charcoal, dusty blue-gray, restrained accent gold; elegant newsroom feel, analytical, calm, precise. Render with sharp axis labels and tick marks, subtle gridlines, balanced whitespace, refined typography, 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.
