What's New

⚡ Performance Improvements for Large Files

This release focuses on preventing browser crashes when working with large JSON files:

Deferred Import Processing

• Files larger than 10KB now use staggered loading
• Line numbers, syntax highlighting, and visualisation updates are deferred using setTimeout
• Prevents the browser from becoming unresponsive during import

Reduced Visualisation Limits

• Maximum nodes reduced from 500 to 300 across all visualisers
• Maximum depth reduced from 20 to 15 to prevent stack overflow
• Visualisation auto-disabled for files larger than 50KB (previously 100KB)

Technical Details

• Import handler now detects large files (>10KB) and defers heavy operations
• Line numbers update deferred by 50ms
• Syntax highlighting deferred by 100ms
• Validation and visualisation deferred by 200ms
• All four visualiser classes (Tree, Force-Directed, Treemap, Sunburst) now share consistent limits
