OBBBA Scatter

Data visualization application showing how tax changes affect American households.

Features

Deep Linking for Households

The application now supports deep linking to specific households, allowing users to:

• Share specific household profiles: Each household can be directly linked via URL
• Bookmark interesting cases: Users can save links to specific households for later reference
• Navigate directly to households: URLs automatically navigate to the appropriate section and household

How to Use Deep Links

1. Automatic URL updates:

   • Navigate to any individual household view
   • The URL automatically updates to include the selected household
   • Copy the URL from your browser's address bar

2. Share the link:

   • Send the URL to others
   • The link will take them directly to that specific household

3. URL format:

   /obbba-scatter/?household=HOUSEHOLD_ID&dataset=DATASET_NAME&section=SECTION_NAME
   

URL Parameters

• household: The unique household ID from the dataset
• dataset: The policy scenario (tcja-expiration or tcja-extension)
• section: The section/view name (optional - will auto-determine based on household income if not provided)

Example URLs

# Direct link to a specific household in the middle-income individual view with TCJA expiration scenario
/obbba-scatter/?household=12345&dataset=tcja-expiration&section=middle-income-individual

# Link to household with TCJA extension scenario and automatic section detection
/obbba-scatter/?household=12345&dataset=tcja-extension

# Link to household with automatic dataset and section detection (defaults to tcja-expiration)
/obbba-scatter/?household=12345

Technical Implementation

• Uses SvelteKit's built-in URL parameter handling
• Automatically maps household income to appropriate sections
• Preserves application state across page reloads
• Smooth scrolling and transitions to the linked household
