🔧 Comprehensive Troubleshooting Guide

❌ Enhanced Navigation Issues ✨

Check Format pane > Navigation settings for zoom controls and minimap visibility
Verify sufficient visual space for navigation controls and minimap
Test cursor feedback during pan operations (should show grab/grabbing)
Ensure minimap viewport rectangle updates correctly during zoom/pan
Test on different screen sizes for responsive behavior

❌ Interactive Legend Problems ✨

Verify categorical field is dragged to “Legend Color (optional)”
Check that nodes have actual colors (not all default gray)
Ensure categorical data contains meaningful, clean values
Test legend click functionality for highlighting behavior
Verify legend positioning doesn’t obstruct main visual content

❌ Proportional Edge Width Issues ✨

Enable “Proportional Width” toggle in Format pane > Edges > General
Ensure Edge Value field contains numeric flow data
Check that EdgeId, SourceId, TargetId are properly mapped
Verify edge data has meaningful variation in values
Test that thickness scaling is visually appropriate

❌ Enhanced Tooltip Problems ✨

Use “Key: Value\nKey2: Value2” format for Node Tooltip field
For Edge Tooltip, drag fields to “Edge Tooltip (optional)” section
Test smart fallback when no Edge Tooltip fields specified
Check that field names appear as labels in tooltip display
Ensure multi-line content displays with proper line breaks

❌ Cross-Filtering Not Working

Add Node Value and/or Edge Value measure fields
Ensure measure values are populated (not NULL/empty)
Test both directions: table → visual and visual → table
Test legend-based filtering independently
Verify selection triggers highlights (opacity changes)
Test with simple single-selection first

❌ Visual Not Displaying

Check that SVG Content measure returns valid SVG markup
Verify NodeId field is mapped and contains data
Ensure SVG element IDs match NodeId values exactly
Validate SVG syntax using an online SVG validator

❌ Nodes Not Interactive

Confirm NodeId data role is populated
Check that SVG elements have matching id attributes
Verify elements are not hidden by other SVG elements
Test hover effects to confirm element detection

❌ Edges Not Showing

Map EdgeId, SourceId, and TargetId data roles
Ensure SourceId/TargetId values match existing NodeId values
Check edge opacity setting (may be set too low)
Verify edge rendering order (foreground vs background)
Test with high contrast edge colors first
