User Experience Flow Chart Infographic with Line Chart Best Practices

Data visualization infographic titled "Line Chart Best Practices" using a TREND LINE (over time) as the dominant visual element. Create an editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout, inspired by NYT graphics desk styling with an Economist warm beige palette: warm beige background, charcoal text, muted rust, deep blue, sage, and soft gold accents. Mood: analytical, elegant, trustworthy, reader-friendly.

Main chart: a large time-series line chart occupying most of the canvas, designed to teach best practices by example. X-axis labeled "Time" with clear English tick marks such as "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec". Y-axis labeled "Value" with evenly spaced ticks from "0" to "100" at sensible intervals. Use a full honest scale with no misleading truncation or manipulation. Plot one primary line in deep blue with realistic illustrative values that show a stable pattern and one notable surprise outlier: Jan 42, Feb 45, Mar 47, Apr 49, May 51, Jun 50, Jul 52, Aug 54, Sep 78, Oct 56, Nov 58, Dec 60. Highlight the September outlier with a contrasting rust marker and a subtle annotation ring. Include light gridlines, sharp axis labels, precise tick marks, and a clean legend if needed labeled "Illustrative series".

Add small secondary best-practice cues around the chart: direct labeling near the line instead of cluttered legend dependence, an unobtrusive annotation pointing to the outlier, balanced white space, and a note visually indicating consistent scale. Avoid decorative clutter. The storytelling angle should clearly emphasize the surprise spike as the main narrative moment.

Include 4 key insight callouts positioned around the chart, each with a small icon, a headline number, and a short interpretation in English:
1. Icon: warning dot. Headline number: "78". Text: "Surprise outlier in September stands well above the trend." 
2. Icon: ruler. Headline number: "0-100". Text: "Honest full-scale axis prevents exaggerated movement." 
3. Icon: eye. Headline number: "1". Text: "One highlighted outlier keeps attention on the main story." 
4. Icon: label tag. Headline number: "12". Text: "Twelve clearly spaced time points improve readability over clutter." 

Add subtle explanatory labels in English near design elements, such as "Direct label", "Outlier annotation", "Even tick spacing", and "Consistent scale", keeping them minimal and editorial.

Include a small bottom strip labeled "Source / Data note" with the exact text: "Illustrative example for chart-design best practices. Values are illustrative, not sourced. No axis truncation or scale manipulation." 

Composition should feel like a polished newspaper data explainer, with the trend line chart dominant, concise annotation layers, and a refined beige-toned newsroom infographic treatment.

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.
