Diagramme de gantt google sheet template roadmap Q1-Q4

Tech architecture infographic titled "Google Sheets Gantt Chart Template Product Roadmap" using HOW-IT-WORKS adapted as a milestone timeline roadmap. Create a one-year Q1-Q4 product roadmap for a Google Sheets Gantt chart template product, presented as a clean milestone timeline with quarter columns and a horizontal time axis. Use structured labeled BOXES as roadmap feature cards and team swim-lane containers, connected by ARROWS to show dependency flow, release progression, and handoff direction between milestones. Include swim lanes such as Product, Template Design, Automation, Collaboration, and Documentation where applicable. Each feature box must include an icon, a canonical English feature name, and a one-line English role description. Use realistic, non-hype feature names such as "Basic Gantt Layout", "Task Dependency Bars", "Milestone Markers", "Conditional Formatting", "Team Timeline View", "Sheet Duplication Setup", "Progress Tracking", "Status Dropdowns", "Print-Friendly View", "Template Instructions", and "Version Update". Add compact status pills on cards with sharp labels: "Planned", "In Progress", "Shipped". Show milestones and releases distributed accurately across Q1, Q2, Q3, and Q4. Add arrows labeled in English with short flow descriptions such as "design spec", "template update", "formula logic", "user feedback", "release handoff", and "documentation publish". Include a numbered legend from 1 to 7 explaining the lifecycle in English, for example: 1. Define roadmap goals, 2. Design core template, 3. Build scheduling logic, 4. Add collaboration features, 5. Validate usability, 6. Ship template updates, 7. Publish supporting documentation. Make the layout visually read like a developer-friendly editorial infographic while still functioning as a roadmap board. Use minimalist Swiss design principles: strict grid, ample whitespace, precise alignment, bold hierarchy, clean sans-serif typography, thin dividers, geometric icons, and disciplined spacing. Apply a high-contrast modern palette with off-white background, deep charcoal text, black or navy structural lines, and sharp accent colors such as electric blue, vivid orange, and lime or emerald for status contrast. Mood: precise, product-focused, modern, trustworthy, editorial developer-blog illustration, isometric or flat tech-diagram style, vector-clean infographic layout. 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.
