Postman Visualizer JSON to Table Bubble Chart Infographic

Data visualization infographic titled "Heatmap Example" using a BUBBLE CHART as the dominant visual element, designed as a 3D scatter-style comparison to show contrast across clusters. Create a large central bubble chart with clear x-axis, y-axis, and depth cue styling, sharp axis labels and tick marks all in English, honest full-scale framing with no misleading truncation or scale manipulation. Use plausible illustrative values because no sourced data was provided. X-axis label: "Intensity" ranging from 0 to 100. Y-axis label: "Frequency" ranging from 0 to 100. Add a subtle depth legend or z-dimension cue labeled "Impact" with bubble size from 10 to 90. Plot contrasting groups with labeled bubbles such as "Low intensity / high frequency", "High intensity / low frequency", "Balanced cluster", "Outlier peak", and "Sparse zone". Example plausible bubble values: Cluster A at 22,78 size 35; Cluster B at 81,24 size 72; Cluster C at 54,51 size 48; Cluster D at 91,88 size 86; Cluster E at 14,19 size 18; Cluster F at 67,63 size 58. Add light gridlines and precise numeric ticks at regular intervals 0, 20, 40, 60, 80, 100 on both axes. Include 4 key insight callouts around the chart, each with a small icon, headline number, and short interpretation in English: "81" — "High-intensity points appear less frequent" with a contrast icon; "78" — "Low-intensity activity forms the densest zone" with a cluster icon; "86" — "Largest bubble marks the strongest combined impact" with an impact icon; "54" — "Mid-range values create the visual balance point" with a balance icon. Add a small source/data-note strip at the bottom reading: "Data note: Illustrative example. Figures are illustrative and not sourced from an external dataset." Visual style: retro 1970s magazine charts, editorial blue & cream palette, muted navy, denim blue, powder blue, cream background, faded ink texture, off-white paper grain, bold vintage typography, geometric annotation boxes, subtle halftone shading, nostalgic editorial 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.
