🚀 Quick Start (5 Minutes)

1. Install Dependencies

pip install -r requirements_v0_6_0.txt

2. Load and Analyze Data

import bizlens as bl

# Load any sample dataset
df = bl.load_dataset('iris')  # or: tips, titanic, school_cafeteria, etc.

# Create analyzer
bd = bl.BizDesc(df, color_scheme='academic')

# Get statistics
cent_tend = bd.central_tendency()

• Symmetric: Bell curve, Mean ≈ Median
• Right-Skewed: Long tail right, Mean > Median
• Left-Skewed: Long tail left, Mean < Median

Plus:

• Skewness numerical value
• Range [Min, Max]
• Standard deviation
• Visual lines for Mean/Median/Mode

2. Sample Datasets Integration (NEW!)

15+ ready-to-use datasets with educational metadata:

• Advanced: breast_cancer, digits, wine
• Synthetic: student_t, normal_dist, exponential_dist

3. Enhanced Visualizations

Before: Basic plots After: Publication-ready with:

• Value labels on bars/pies
• Distribution annotations
• Professional coloring
• Bold formatting
• Statistical overlays

4. Variance & Standard Deviation

Prominent display of:

• Variance formula: σ² = Σ(x - μ)² / (n - 1)
• Standard Deviation: σ = √variance
• 68-95-99.7 rule explained
• Interpretation in context
