Graph Online Maker Free Streamgraph Trend Infographic

Data visualization infographic titled "Streamgraph Topic Over Time" using TREND LINE (over time) as the dominant visual element. Create a large editorial time-series chart with one main line and subtle supporting context bands, focused on revealing a clear surprise outlier. X-axis labeled in English with exact text "Time" and evenly spaced tick marks from "Jan" to "Dec". Y-axis labeled in English with exact text "Relative Search Interest" and full baseline starting at 0, clear tick marks at "0", "20", "40", "60", "80", "100" to avoid misleading truncation. Plot a plausible illustrative trend for the topic with low-to-moderate activity for most of the year and one sharp unexpected spike: Jan 12, Feb 15, Mar 18, Apr 22, May 24, Jun 28, Jul 31, Aug 29, Sep 34, Oct 88, Nov 41, Dec 36. Mark the October peak prominently with a contrasting highlight dot and annotation ring. Include light secondary mini-lines or faint comparison traces in the background only if they do not compete with the main trend.

Add 4 key insight callouts with small icons, each in English: 1) icon magnifying glass, headline number "88", interpretation "Illustrative peak in October, far above the yearly norm"; 2) icon lightning bolt, headline number "+54", interpretation "Largest month-to-month jump from September to October"; 3) icon ruler, headline number "27", interpretation "Illustrative average level across the rest of the year"; 4) icon warning triangle, headline number "3.3x", interpretation "October sits at more than triple the baseline pattern". Place callouts around the chart with thin leader lines, clean editorial positioning, and concise labels.

Include a small annotation near the outlier with exact English text "Surprise spike" and a short caption "A sudden breakout point stands apart from the prior pattern". Add a compact side note box with exact English text "Why it matters" and body text "Outliers can reveal shifts in attention, product launches, algorithm changes, or news-driven discovery".

Add a bottom SOURCE / DATA-NOTE strip in English with exact text "Data note: Illustrative example. Values are plausible sample figures for demonstration only, not sourced measurements." Keep this strip subtle and clearly separated from the main chart.

Visual style: NYT graphics desk meets Economist warm beige palette, editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. Use warm beige background, soft cream plotting area, charcoal typography, muted brown and sand neutrals, with one restrained accent color such as deep rust or muted red to emphasize the outlier. Minimalist, intelligent, analytical mood; precise gridlines; sharp axis labels and tick marks; balanced whitespace; elegant legend treatment if used; no 3D effects; no clutter; no decorative elements that reduce readability. Ensure labels are crisp and all metric names, captions, and legends are in English. No misleading axis scaling, no truncated y-axis, no fake authoritative sources cited, no watermarks. 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.
