Examples

1. Software Development Lifecycle

Project Manager
Background
Managing a 3-month software development project with multiple phases and hand-offs.
Problem
Difficulty in visualizing how the design phase impacts the development start date.
How to Use
Input the phase names, dates, and dependencies into the task JSON field, then enable 'Show Dependencies'.
Example Config
[{"name": "Design", "startDate": "2024-01-01", "endDate": "2024-01-15", "progress": 100}, {"name": "Development", "startDate": "2024-01-16", "endDate": "2024-02-28", "progress": 60, "dependencies": ["task-0"]}]
Outcome
A clear timeline showing the development phase starting immediately after the design phase, with progress bars reflecting current status.

2. Marketing Campaign Timeline

Marketing Lead
Background
Coordinating a product launch with various content creation and advertising tasks.
Problem
Need to highlight the final launch date as a critical milestone for the team.
How to Use
Add a task with 'isMilestone: true' to the JSON input and set the milestone color to a high-visibility orange.
Example Config
{"milestoneColor": "#f59e0b", "showMilestones": true}
Outcome
A professional chart displaying the launch date as a distinct milestone, ensuring the team stays focused on the target deadline.
