VizlyChart - Interactive Examples

## 🤖 AI-Driven Chart Generation

Create charts using natural language descriptions and get intelligent recommendations

import vizlychart as vc import numpy as np # Generate sample data data = { 'sales': np.random.normal(10000, 2000, 100), 'price': np.random.uniform(50, 200, 100) } # Natural language chart creation chart = vc.ai.create("scatter plot of sales vs price") # Get smart recommendations rec = vc.recommend_chart(data, intent='correlation') print(f"Recommended: {rec.chart_type}") print(f"Confidence: {rec.confidence:.0%}")

### Live Demo Results:

✅ AI Engine Active
Recommended: scatter
Confidence: 90%
📊 AI-Generated Scatter Plot

AI Reasoning:

- Two numeric variables detected
- Correlation analysis requested
- Scatter plot optimal for this relationship

## 🔄 Multi-Backend Support

Switch between visualization backends seamlessly without changing code

# Check available backends backends = vc.list_backends() print(f"Available: {[b.value for b in backends]}") # Switch to Plotly for interactive charts vc.set_backend('plotly') chart = vc.LineChart() chart.plot(x, y) # Interactive, web-ready # Switch to matplotlib for publication quality vc.set_backend('matplotlib') chart = vc.LineChart() chart.plot(x, y) # Same API, different output # Switch to pure Python for performance vc.set_backend('pure') chart = vc.LineChart() chart.plot(x, y) # GPU-accelerated

### Backend Status:

✅ matplotlib: Production Ready
✅ plotly: Interactive Web
✅ pure: GPU Accelerated

## 🧠 Machine Learning & Causal Inference

Specialized visualizations for data science and ML explainability

# Causal Directed Acyclic Graph dag = vc.CausalDAGChart() dag.add_node("Treatment", "treatment") dag.add_node("Outcome", "outcome") dag.add_node("Confounder", "confounder") dag.add_edge("Treatment", "Outcome") dag.auto_layout("hierarchical") # Feature Importance Analysis features = ['age', 'income', 'education'] importance = np.array([0.4, 0.35, 0.25]) fi_chart = vc.FeatureImportanceChart() fi_chart.plot(features, importance, "shap") # Model Performance Comparison models = {'RF': (0.85, 0.82), 'SVM': (0.82, 0.80)} perf_chart = vc.ModelPerformanceChart() perf_chart.plot_roc_curves(models)

### ML Visualization Results:

✅ Causal DAG: 3 nodes, 1 edge
✅ Feature Importance: SHAP analysis
✅ ROC Curves: Model comparison
🕸️ Causal DAG Visualization

Advanced Features:

- Automatic graph layout algorithms
- SHAP waterfall explanations
- Interactive model performance metrics
- Confusion matrix heatmaps

## ⚡ High-Performance Rendering

GPU-accelerated visualization for large datasets

from vizlychart.gpu import AcceleratedRenderer # Create GPU-accelerated renderer renderer = AcceleratedRenderer(1200, 800) # Generate large dataset n_points = 50000 x = np.random.randn(n_points) y = np.random.randn(n_points) # GPU-accelerated scatter plot import time start = time.time() renderer.scatter_gpu(x, y, color='blue', size=3) render_time = time.time() - start # Get performance statistics stats = renderer.get_performance_stats() print(f"Rendered {n_points:,} points in {render_time:.3f}s")

## 🎨 Natural Language Styling

Style charts using intuitive natural language descriptions

# Style charts with natural language vc.style_chart(chart, "professional blue theme with bold fonts") # Parse different styling descriptions styles = [ "elegant pastel colors with shadows", "minimal design with thin gray lines", "vibrant colors with large points", "scientific monochrome theme" ] for description in styles: style_config = vc.ai.parse_style(description) print(f"'{description}'") print(f" Theme: {style_config.overall_theme}") print(f" Colors: {style_config.color_scheme}") # Apply styling to existing chart stylist = vc.NaturalLanguageStylist() stylist.apply_to_chart(chart, style_config)

### Styling Results:

✅ Style Parser: Active
Theme: business
Colors: professional
🎨 Professional Blue Theme

Parsed Elements:

- Color scheme: Professional blue palette
- Typography: Bold, business fonts
- Layout: Clean, structured design
- Theme: Corporate/professional style
