# Timeline Builder Generate beautiful interactive timeline HTML pages from JSON configuration data, with three layout modes: 1. **Vertical layout (`vertical`)** — A classic top-to-bottom timeline with event cards alternating on either side of the axis 2. **Horizontal layout (`horizontal`)** — A horizontally scrollable timeline, best for displaying fewer events 3. **Dual-side layout (`dual-side`)** — Events are placed on the left or right based on the `side` field, great for side-by-side comparisons All layouts support: - Click to expand/collapse event details - Mobile-friendly responsive design - Custom theme colors, icons, and category labels - Pure static HTML with zero dependencies — opens directly in any browser ## Usage ### Basic: Generate from a JSON config file ```bash python3 scripts/generate_timeline.py --config timeline_data.json --output timeline.html ``` ### Read JSON from stdin ```bash cat timeline_data.json | python3 scripts/generate_timeline.py --stdin --output timeline.html ``` ### Override layout mode (takes precedence over config file) ```bash python3 scripts/generate_timeline.py --config data.json --layout horizontal --output timeline.html ``` ### JSON Configuration Format ```json { "title": "Project Milestones", "layout": "vertical", "theme": { "primaryColor": "#2563eb", "secondaryColor": "#7c3aed", "backgroundColor": "#ffffff", "textColor": "#1f2937", "lineColor": "#d1d5db", "fontFamily": "system-ui, -apple-system, sans-serif" }, "events": [ { "date": "2024-01-15", "title": "Project Kickoff", "summary": "Approval completed, core team assembled", "details": "Detailed description text, shown when the card is expanded...", "icon": "🚀", "category": "Milestone", "color": "#10b981", "side": "left" } ] } ``` ### CLI Arguments | Argument | Description | |----------|-------------| | `--config, -c` | Path to the JSON config file (mutually exclusive with `--stdin`) | | `--stdin` | Read JSON from standard input | | `--output, -o` | Output HTML file path (defaults to stdout) | | `--layout, -l` | Override layout mode: `vertical`, `horizontal`, `dual-side` | | `--title, -t` | Override the timeline title | ### Event Fields | Field | Required | Description | |-------|----------|-------------| | `date` | Yes | Date label — any format works (e.g. `2024-01`, `Q1 2024`, `Phase One`) | | `title` | Yes | Event title | | `summary` | No | Short description, always visible on the card | | `details` | No | Detailed content, revealed on click | | `icon` | No | Emoji or single-character icon (defaults to `●`) | | `category` | No | Category tag displayed on the card | | `color` | No | Event node color (overrides the theme color) | | `side` | No | Only for dual-side layout: `left` or `right` | ## Use Cases - Project milestone displays - Product release histories - Company growth timelines - Personal resume timelines - Course syllabus outlines - Any scenario requiring chronological information display ## Dependencies - Python 3.6+ (standard library only — no extra packages required) ## Activation Triggers Triggered when a user mentions 'timeline', 'history of events', 'project milestones', 'release log', or asks to visualize a chronological sequence of data.
