Grafana Sankey Style Gantt Chart Project Variance Infographic

Data visualization infographic titled "Gantt Chart Project" using COMPARISON COLUMNS as the dominant visual element, designed to communicate project schedule variance and highlight the surprise outlier. Create a large ranked set of vertical comparison columns showing planned duration versus actual duration for key project phases, with each phase labeled in English on the x-axis: "Discovery", "Design", "Development", "Testing", "Integration", "Launch". Use two columns per phase: "Planned Days" and "Actual Days". Use realistic illustrative numbers: Discovery 10 vs 12, Design 15 vs 14, Development 30 vs 33, Testing 12 vs 28, Integration 8 vs 9, Launch 5 vs 5. Make "Testing" the clear outlier with a visibly much taller actual column. Include a y-axis labeled "Duration (days)" with clear tick marks from 0 to 35 at 5-day intervals, no truncated axis, no misleading scaling. Add a subtle secondary annotation above the chart: "Illustrative project schedule variance". 

Add 4 key insight callouts around the chart, each with a small minimal icon in monochrome ink style: 1) headline number "28 days" with interpretation "Testing took more than twice the planned time" and a warning icon; 2) headline number "+16 days" with interpretation "Testing created the largest overrun in the schedule" and a spotlight icon; 3) headline number "89 days" with interpretation "Total actual timeline exceeded the 80-day plan" and a calendar icon; 4) headline number "3 phases" with interpretation "Most phases stayed close to plan despite one major delay" and a checkmark icon. 

Include sharp English labels, legend, captions, and tick marks. Add a compact legend in English: "Planned Days" and "Actual Days". Add a small annotation arrow or bracket calling out the outlier column pair with text: "Unexpected delay concentrated in Testing". 

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, black, and one darker ink accent for the outlier. Clean newsroom layout, precise spacing, restrained typography, high-clarity gridlines, subtle paper-finance feel, analytical and credible mood. 

Add a small bottom strip in English: "Data note: Figures are illustrative example values for visual demonstration only." and "Source: Illustrative example". Do not include any fake institutional or media source. 

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.
