Sankey Plot Style Heatmap Example Donut Chart Infographic

Data visualization infographic titled "Heatmap Example" using a PIE / DONUT (composition) chart as the dominant visual element to show contrast clearly. Center a large multi-ring donut chart with sharp English labels, clean segment dividers, precise percentage annotations, and subtle radial guides; include clear tick marks and measurement guides around the composition for dashboard-style readability, all in English. Use realistic illustrative values such as: "High Intensity" 42%, "Medium Intensity" 28%, "Low Intensity" 18%, "Minimal Activity" 12%. Surround the donut with a compact secondary mini heatmap panel for context only, visually supporting the topic while keeping the donut dominant. Add 4 key insight callouts with small icons: 1) headline number "42%" with interpretation "High Intensity dominates the pattern" and a flame icon, 2) headline number "14 pts" with interpretation "Gap between High and Medium intensity is pronounced" and a contrast icon, 3) headline number "60%" with interpretation "Top two bands make up most of the total" and a stacked-layers icon, 4) headline number "12%" with interpretation "Minimal Activity remains a small share" and a dim-circle icon. Include a small English legend with exact labels: "High Intensity", "Medium Intensity", "Low Intensity", "Minimal Activity". Add a bottom strip reading exactly: "Data note: Illustrative example only. Figures are not sourced real-world data." Ensure no misleading scale tricks, balanced proportions, and no fake authoritative source. Visual style: dark dashboard interface, FT pink and deep navy palette with soft magenta highlights, muted gridlines, high-contrast typography, elegant financial-newsroom mood. Include 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.
