Google Geocharts Radar Spider Chart Sankey Infographic

Data visualization infographic titled "Radar Spider Chart" using a SANKEY FLOW as the dominant visual element to show progress through a pipeline. Main structure: a left-to-right sankey with 5 sequential stages labeled in English: "Raw Data", "Normalization", "Metric Grouping", "Radar Axes", "Final Spider Chart". Use realistic plausible illustrative values flowing through stages, for example 100%, 92%, 84%, 78%, 72%, with branch losses clearly labeled "Filtered", "Cleaned", "Grouped", "Finalized". Make widths proportional and visually clear, with sharp English labels, clean connector geometry, precise stage separators, and small baseline tick references beneath the flow showing progress checkpoints "0%", "25%", "50%", "75%", "100%" in English. Include a subtle secondary inset mini-radar chart preview at the far right labeled "Final Spider Chart Preview" to connect the sankey pipeline to the topic, but keep the sankey as the dominant chart.

Add 4 key insight callouts placed around the main flow, each with a small icon, headline number, and short interpretation in English: 1) "100%" — "Initial metrics enter the workflow" with database icon; 2) "84%" — "Most values survive normalization and cleaning" with filter icon; 3) "22 pts" — "Largest drop happens before final axis grouping" with warning/attention icon; 4) "72%" — "Final chart-ready share after processing" with radar/signal icon. Mark these figures as illustrative in small text where appropriate: "Illustrative".

Design style: NYT graphics desk clarity with Economist warm beige palette; warm beige background, muted sand panels, charcoal text, dark espresso outlines, soft red-orange accent for losses, muted blue-gray accent for completed progress, restrained olive or ochre highlights. Editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. Balanced margins, subtle grid, elegant typography, understated newsroom seriousness, no 3D effects, no clutter.

Add a small source/data-note strip at the bottom in English: "Data note: Illustrative example. Values shown are sample figures for visualization only unless sourced by the user." Ensure no misleading axis truncation or scale manipulation; keep all progress references honest and clearly proportional. 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.
