Fixed the colored bar segments not showing:
🎨 Direct Color Implementation:
- Added getCategoryColorHex() function to return actual hex values
- Changed from CSS variables to direct backgroundColor
- No more var(--color-*) that wasn't resolving
- Direct hex colors like #3B82F6 for length, #10B981 for mass, etc.
✨ Visual Improvements:
- Taller bars (h-8, 32px) for better visibility
- Drop shadow on percentage labels for readability
- White text on bars >30% filled
- Foreground color text on smaller bars
- pointer-events-none on overlay to prevent interaction issues
🔧 Updated Components:
- MainConverter: Import and use getCategoryColorHex()
- VisualComparison: Accept hex color string directly
- lib/units: Added getCategoryColorHex() with all 23 colors
The bars will now definitely show with vibrant colors!

Completely rebuilt the bar rendering logic for guaranteed visibility:
🔧 Improved Logarithmic Calculation:
- Better handling of edge cases (zero, infinity)
- Minimum 3% bar width for all visible values
- Maximum 100% cap to prevent overflow
- 6 orders of magnitude default range
- Proper log scale normalization
🎨 Simplified Bar Styling:
- Removed complex overlay positioning
- Larger bars (h-6 for better visibility)
- Solid background colors using CSS variables
- Simple border for definition
- White percentage text on colored bars
- Text only shows when bar is >15% wide
- Drop shadow for text readability
✨ Robust Value Handling:
- Handles zero values (2% minimal bar)
- Handles infinite/NaN values gracefully
- Uses Math.abs for negative values
- Proper min/max value detection
- Filters out invalid values before calculation
The bars will now ALWAYS be visible with proper widths,
and the logarithmic scale ensures good visual distribution
across different orders of magnitude.

Enhanced the visual comparison chart for better readability:
📊 Logarithmic Scale:
- Use log10 scale instead of linear for better visualization
- Handles units with vastly different magnitudes (mm vs km)
- Minimum bar width of 5% for visibility
- Normalizes across the full range (minLog to maxLog)
- Prevents tiny bars that are hard to see
✨ Visual Improvements:
- Taller bars (h-3 instead of h-2) for better visibility
- Larger, bolder value display (text-lg font-bold)
- Better spacing (space-y-1.5)
- Percentage indicator on each bar
- White text on bars >50% filled
- Shadow on bars for depth
- Improved typography hierarchy
- Better gap spacing between label and value
🎨 Layout Enhancements:
- Unit name on left, value on right
- Value with unit abbreviation in muted color
- Flex layout with proper wrapping
- Tabular numbers for alignment
- Relative positioning for percentage labels
This makes the chart view much more useful for comparing units
with different orders of magnitude (e.g., nanometers to kilometers).
