Highlight Table in Tableau Line Chart Best Practices Infographic

Data visualization infographic titled "Line Chart Best Practices" using a TREND LINE (over time) as the dominant visual element. Show a clean editorial example of a time series with one clear surprise outlier and best-practice annotations. Main chart: a large sharp line chart with x-axis labeled "Month" and y-axis labeled "Value (Illustrative Index)"; tick marks must be evenly spaced, zero-baseline visible where appropriate, no misleading axis truncation, no distorted scale manipulation. Use a plausible illustrative dataset across 12 months: Jan 72, Feb 74, Mar 73, Apr 76, May 78, Jun 79, Jul 81, Aug 80, Sep 82, Oct 118, Nov 84, Dec 86. Make the main series a dark ink line, with the October point emphasized as the outlier using a contrasting heavier marker ring and a thin annotation leader. Add subtle reference aids: light gridlines, a faint moving-average guide line, and a small shaded band labeled "Typical range" spanning roughly 72-86 for most months to visually reveal the surprise spike. Include concise best-practice annotation labels directly on the chart in English such as "Clear baseline", "Readable ticks", "Highlight the outlier", and "Consistent scale". Add 4 key insight callouts around the chart, each with a small simple icon: 1) headline number "118" with interpretation "October spike stands far above the typical range" and an alert icon; 2) headline number "+36" with interpretation "Outlier is 36 points above September" and an upward arrow icon; 3) headline number "72-86" with interpretation "Most months cluster in a stable band" and a range/bracket icon; 4) headline number "0 truncation" with interpretation "Avoid cropped y-axis that exaggerates change" and a ruler icon. Add a small side panel titled "Best practices" with short bullets in English: "Use direct labels where possible", "Annotate unusual events", "Keep scales honest", "Reduce chartjunk", "Use contrast sparingly". Add a compact mini-panel titled "What not to do" showing a tiny incorrect example with a truncated axis and label "Misleading" crossed subtly. Add a small SOURCE / DATA-NOTE strip at the bottom reading "Data note: Illustrative example for design best practices. Figures are illustrative, not sourced real-world data." Visual style: editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout, monochrome ink palette with off-white background, charcoal, soft gray, deep ink navy accents, restrained high-contrast highlights only for the outlier, precise typography, spacious margins, calm analytical mood, print-quality financial-news graphic clarity. 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.
