Visualizacion de data con bubble chart y trendline

Data visualization infographic titled "Scatter Plot Trendline" using BUBBLE CHART as the dominant visual element to best show the trend. Create a dark dashboard layout with FT pink and navy palette: deep navy background, soft pink trend accents, muted slate gridlines, off-white text, subtle magenta highlights. Main chart: a large scatter plot with a clear upward trendline, sharp x-axis and y-axis labels, evenly spaced tick marks, thin grid, and no misleading axis truncation or scale manipulation. Use realistic plausible illustrative values. X-axis label in English: "Time Period" with ticks "1", "2", "3", "4", "5", "6", "7", "8", "9", "10". Y-axis label in English: "Performance Index" with ticks "0", "10", "20", "30", "40", "50", "60", "70", "80", "90", "100". Plot around 14-18 bubbles in navy and pink tones, varying slightly in size, clustered along an upward trajectory from lower-left to upper-right. Add a fitted line labeled exactly "Trendline" and a small legend labeled exactly "Illustrative data". Include a subtle secondary pipeline motif in the side panel as decorative support only, not the main data encoding.

Add 4 key insight callouts around the chart, each with a small icon, headline number, and short interpretation in English:
1. "72" — "Latest period sits well above the early baseline" with an upward arrow icon.
2. "+38 pts" — "Overall gain from first to last illustrative period" with a delta icon.
3. "0.86" — "Strong positive correlation in the illustrative sample" with a link/chart icon.
4. "3 high points" — "Several observations outperform the central trend" with a spark/star icon.

Add a compact annotation near the line reading exactly "Steady upward trend". Include a small side metric strip with labels exactly "Start", "Midpoint", "End" and values "34", "56", "72". Add a small SOURCE / DATA-NOTE strip at the bottom in English reading exactly: "Data note: Illustrative example. Figures shown are sample values for visualization layout only." Keep all labels crisp and editorial. Visual style: editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout, polished dashboard mood, analytical and modern. 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.
