/**
 * Mobile Chart Optimizations
 *
 * Optimizes ApexCharts and other chart libraries for mobile viewing
 * Based on patterns from Power BI Mobile, Looker, Tableau
 *
 * Key optimizations:
 * 1. Reduced chart heights
 * 2. Simplified legends (bottom, smaller text)
 * 3. Reduced axis label density
 * 4. Smaller fonts throughout
 * 5. Touch-friendly tooltips
