Data Visualization in Cloud Computing Bubble Chart Infographic

Data visualization infographic titled "Pie Chart vs Donut" using a BUBBLE CHART as the dominant visual element to show the contrast between pie charts and donut charts. Create a clean 3D scatter-style bubble chart with sharp axis labels and tick marks in English: x-axis labeled "Category Count", y-axis labeled "Label Readability", z-axis/depth concept labeled "Space Efficiency". Plot two main compared bubbles prominently: "Pie Chart" and "Donut Chart", plus a few smaller contextual bubbles such as "Small Segments", "Center Annotation", and "Total Value Display" to enrich the comparison. Use realistic plausible illustrative values only, clearly framed as illustrative. Show balanced scales with no misleading truncation or manipulation.

Add 4 key insight callouts around the chart, each with a small icon, a headline number, and a short interpretation in English: 1) "12 categories" — "Donut layouts stay easier to annotate when many slices compete" with an annotation icon. 2) "18% more center space" — "Donut charts create room for totals or KPI summaries" with a target icon. 3) "2 chart types" — "Pie emphasizes whole-part comparison, donut improves dashboard integration" with a compare icon. 4) "5+ small slices" — "Both formats become harder to scan when categories are too fragmented" with an eye icon.

Include small labels near bubbles with exact rendered English text: "Pie Chart", "Donut Chart", "Small Segments", "Center Annotation", "Total Value Display", "Higher readability", "More categories", "Better space efficiency". Include a compact legend titled "Contrast Factors" with rainbow categorical colors assigned consistently to comparison dimensions.

Add a small source / data-note strip at the bottom in English with exact text: "Data note: Illustrative example only. Values are conceptual and not sourced from external datasets." Also add a tiny note: "Not to scale beyond the shown illustrative axes." 

Visual style: minimal flat, rainbow categorical palette, lots of white space, crisp vector shapes, subtle depth cues for 3D scatter bubbles without photorealism, modern editorial layout, calm analytical mood. Use 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.
