• Repository Fetching: Retrieve all public repositories for a user
• Timeline Generation: Create chronological visual representation
• Validation: Handle invalid usernames with informative error messages

Data Processing

• Repository Analysis: Extract key information:
  • Repository names and descriptions
  • Creation dates for chronological ordering
  • Programming languages used
  • Star counts and fork counts (bonus)
• Date Sorting: Organize repositories by creation date
• Data Filtering: Show only public repositories

Visual Design

• Professional Timeline: Create visually appealing timeline layout
• Typography: Effective use of fonts and text hierarchy
• Color Scheme: Professional color palette suitable for presentations
• Responsive Layout: Works well on different screen sizes
• Visual Hierarchy: Clear organization of repository information

User Experience

• Loading States: Progress indicators during API calls
• Error Handling: Clear error messages for various failure scenarios
• Shareable Results: Timeline suitable for portfolio presentation
