Ultimate Excel Gantt Chart for Project Management Roadmap

Tech architecture infographic titled "Ultimate Excel Gantt Chart for Project Management" using HOW-IT-WORKS archetype, adapted as a quarterly product roadmap for the next 3 months. Show a clean roadmap board with a horizontal timeline axis covering Month 1, Month 2, Month 3 within the next quarter, with quarter label accurate and clearly placed. Organize content into swim lanes by team where applicable, such as Product, Spreadsheet Engineering, Templates, UX, and Documentation. Render labeled BOXES and feature cards/pills for each roadmap item, each with a small icon, a feature name in canonical English, and a one-line role description in English. Use status indicators with sharp readable labels: Planned, In Progress, Shipped. Connect related boxes with ARROWS showing dependency or workflow direction, each arrow labeled in English with what passes between stages, such as "user feedback", "template update", "formula logic", "Excel sample file", "release notes", "bug fix". Include realistic, non-overpromising feature names such as "Template Library Refresh", "Milestone Dependency View", "Conditional Formatting Presets", "Task Progress Rollup", "Print-Friendly Timeline Layout", "Date Validation Rules", "Import CSV Task List", "Example Project Workbook", "Quick Start Guide Update", "Status Color Legend", "Resource Row Grouping", "Baseline Comparison Sheet". Each box should feel like a roadmap feature card rather than infrastructure, but still follow tech-diagram logic with arrows and grouped stages. Add a numbered legend (1-7) walking through the delivery lifecycle in English, for example: 1. Research top user pain points, 2. Prioritize spreadsheet improvements, 3. Build and test formulas, 4. Refine visual timeline layout, 5. Prepare sample workbook assets, 6. Release completed improvements, 7. Collect feedback for next cycle. Visual style: warm boutique, editorial developer-blog illustration, isometric or flat tech-diagram style, vector-clean infographic layout. Color palette: deep navy base, warm beige background, muted terracotta, soft gold, warm coral accents, subtle cream panels. Mood: polished, premium, approachable, thoughtful, boutique product strategy. Emphasize quarter columns, timeline axis, feature pills, swim lanes, and crisp status chips. Keep the infographic visually optimized for the search intent around an Excel Gantt chart for project management, but without rendering the search-intent phrase as explicit on-image text. 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 real cloud-vendor logos (AWS / GCP / Azure) — use generic cloud icons, no watermarks Status labels rendered sharp. Realistic feature names — no overpromising. Quarter / horizon labels accurate.
