## 🚀 Performance Optimization Tips

### GPU Acceleration
```python
# Use GPU for data generation
import cupy as cp

# Generate large datasets on GPU
x_gpu = cp.linspace(0, 10*cp.pi, 100000)
y_gpu = cp.sin(x_gpu) * cp.exp(-x_gpu/50)

# Transfer to CPU for visualization
x = cp.asnumpy(x_gpu)
y = cp.asnumpy(y_gpu)
```

### Memory Optimization
```python
# Use SVG_ONLY quality for maximum speed
from vizlychart.rendering.vizlyengine import RenderQuality

chart = vc.LineChart(quality=RenderQuality.SVG_ONLY)

# Downsample large datasets for visualization
downsample_factor = len(data) // 1000
x_vis = x[::downsample_factor]
y_vis = y[::downsample_factor]
```

### Batch Processing
```python
# Process multiple charts efficiently
charts = []
for dataset in large_datasets:
    chart = vc.LineChart(width=800, height=600)
    chart.plot(dataset.x, dataset.y)
    charts.append(chart)

# Save all at once
for i, chart in enumerate(charts):
    chart.save(f'chart_{i}.svg')
```

y = simulate_complex_system(x)   # GPU-accelerated simulation

chart = vc.LineChart(width=1200, height=800)
chart.plot(x[::50], y[::50])    # Downsample for visualization
chart.set_title('50K Point Simulation Results')
```

### Financial Analysis
```python
# High-frequency trading data
prices = gpu_process_market_data(ticker, days=365)  # GPU processing
ma_20 = gpu_moving_average(prices, 20)
ma_50 = gpu_moving_average(prices, 50)

chart = vc.LineChart(width=1400, height=900)
chart.plot(dates, prices, label='Price', line_width=1.5)
chart.plot(dates, ma_20, label='MA 20', line_width=2.0)
chart.plot(dates, ma_50, label='MA 50', line_width=2.0)
```

### Engineering Simulations
```python
# CFD/FEA result visualization
mesh_data = gpu_solve_equations(mesh, boundary_conditions)
stress_field = extract_stress_field(mesh_data)

chart = vc.ScatterChart(width=1000, height=1000)
for point, stress in zip(mesh.points, stress_field):
    color_intensity = stress / max_stress
    color = vc.ColorHDR(color_intensity, 0, 1-color_intensity, 0.8)
    chart.scatter([point.x], [point.y], c=color, s=5.0)

5. **Real-time Rendering**: Interactive visualization techniques

## 🐛 Troubleshooting

### Common Issues

**GPU Not Detected**
```python
# Verify GPU availability
import torch
print("GPU Available:", torch.cuda.is_available())

# Use CPU fallback if needed
chart = vc.LineChart(quality=RenderQuality.FAST)  # CPU optimized
```

**Memory Errors**
```python
# Reduce dataset size
data_subset = large_dataset[::10]  # Take every 10th point

# Use memory-efficient processing
for batch in data_batches:
    process_batch(batch)
    torch.cuda.empty_cache()  # Clear GPU memory
```

**Slow Rendering**
```python
# Use SVG-only mode
chart = vc.LineChart(quality=RenderQuality.SVG_ONLY)

# Reduce visual complexity
chart.plot(x, y, line_width=1.0)  # Thinner lines render faster
```
