Daten visualisieren mit Bubble-Chart-Infografik

Data visualization infographic titled "Pie Chart vs Donut Chart" using a BUBBLE CHART as the dominant visual element to show the contrast between the two chart types. Create a clean 3D scatter / bubble-chart composition with sharp x-axis and y-axis labels, visible tick marks, subtle gridlines, and a clearly readable legend, all in English. Use the x-axis label "Data Density" and the y-axis label "Label Readability". Add a visual size encoding for bubbles labeled "Space Efficiency" and a small legend note "Bubble size = relative space efficiency". Plot two main featured bubbles prominently: "Pie Chart" and "Donut Chart", with realistic illustrative comparison values. Use plausible illustrative metrics such as Pie Chart: Data Density 42, Label Readability 58, Space Efficiency 72; Donut Chart: Data Density 55, Label Readability 74, Space Efficiency 64. Add a few secondary faint comparison bubbles for context, such as "Stacked Bar" 68/81/59 and "Treemap" 61/49/78, but keep Pie Chart and Donut Chart as the editorial focus.

Include 4 key insight callouts around the chart, each with a headline number, a short interpretation in English, and a small icon: 1) "74" with text "Donut charts often improve central-label placement" and a small center-label icon. 2) "72" with text "Pie charts can use slightly more full-area space" and a small circle-fill icon. 3) "+16 pts" with text "Donut leads on label readability in this illustrative example" and a small eye icon. 4) "42 vs 55" with text "Donut handles added annotation better in dense layouts" and a small tag icon. Mark each metric or callout that uses made-up figures with a tiny label "Illustrative".

Add a side annotation panel titled "How to Read This" with short English notes: "Higher up = easier labels", "Further right = better handling of dense information", "Larger bubble = more space efficiency". Include a small contrast caption in English: "Pie emphasizes whole-area perception; donut adds room for center messaging." Ensure no misleading axis truncation or scale manipulation; axes should start at 0 and use honest intervals such as 0, 20, 40, 60, 80, 100.

Visual style: retro 1970s magazine charts, editorial blue and cream palette, slightly muted ink blues, warm cream background, navy labels, dusty slate-blue bubbles, and subtle vintage print texture. Mood: analytical yet warm, stylish editorial comparison. Use geometric icons, period-authentic typography feel, tidy annotation lines, and balanced negative space. Include editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout.

Add a small bottom strip in English labeled "Source / Data note" with the exact text: "Illustrative example. Figures shown are conceptual and not sourced from an external dataset." Do not cite any fake organizations or authoritative sources.

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.
