Python Geo Map Visualization Trend Line Infographic

Data visualization infographic titled "Sankey Diagram Example" using a TREND LINE (over time) as the dominant visual element. Show a dark dashboard-style editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. Use a deep navy background, FT pink primary line, softer pink highlight for the outlier point, muted slate gridlines, and light gray-white typography for contrast. Overall mood: analytical, premium, surprising outlier focus.

Main chart: a large single time-series line chart centered on the canvas with sharp axis labels and tick marks, all in English. X-axis label: "Month" with ticks "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec". Y-axis label: "Flow Volume (Illustrative Units)" with evenly spaced ticks from 0 to 180 in increments of 20, no truncated axis, no misleading scale manipulation. Plot realistic plausible illustrative values showing a stable pattern with one surprising outlier: Jan 62, Feb 66, Mar 64, Apr 69, May 71, Jun 68, Jul 73, Aug 128, Sep 76, Oct 79, Nov 81, Dec 84. Emphasize the August spike with a glowing marker, annotation ring, and subtle contrast shading. Add a small subtitle above the chart: "Illustrative monthly flow pattern with one unexpected surge".

Add contextual design cues inspired by flow analytics without turning it into a Sankey chart: faint background node-and-link motifs, thin directional connectors, and micro-diagram accents near the margins.

Include 4 key insight callouts positioned around the chart, each with a headline number, a short interpretation in English, and a small icon:
1. Headline number: "128"; interpretation: "August spikes far above the baseline, signaling the clear outlier month."; icon: small alert / spark icon.
2. Headline number: "+75%"; interpretation: "The jump from July to August is the steepest month-to-month change in the series."; icon: upward arrow icon.
3. Headline number: "73-84"; interpretation: "Outside the spike, late-year values return to a relatively narrow operating range."; icon: stability / slider icon.
4. Headline number: "12"; interpretation: "A full-year view makes the anomaly easier to spot than a single-period snapshot."; icon: calendar icon.

Add a compact legend in English: "Monthly Flow", "Outlier Month", "Typical Range". Use crisp chart furniture, subtle gridlines, clear point markers, and precise annotation arrows. Include a small source / data-note strip at the bottom in English reading: "Data note: Illustrative example only. Figures are plausible sample values for layout demonstration and are not sourced observations." 

Do not include any rendered on-image text about the search intent phrase; reflect the concept visually only through subtle geo-analytics cues if needed. All labels written in English should be quoted exactly as rendered, including: "Sankey Diagram Example", "Illustrative monthly flow pattern with one unexpected surge", "Month", "Flow Volume (Illustrative Units)", "Monthly Flow", "Outlier Month", "Typical Range", and "Data note: Illustrative example only. Figures are plausible sample values for layout demonstration and are not sourced observations."

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.
