## Sweetviz with Jupyter Magic


```python
# In Jupyter notebook
import sweetviz as sv
import pandas as pd

# Load data
df = pd.read_csv("data.csv")

# Quick analysis (opens in new tab)
report = sv.analyze(df)
report.show_notebook()  # Opens in browser from notebook

# Inline display (for newer Jupyter versions)
report.show_notebook(
    w="100%",  # Width
    h="600px",  # Height
    scale=0.8  # Scale factor
)

# For comparison
train_df = df.sample(frac=0.8)
test_df = df.drop(train_df.index)

comparison = sv.compare(
    [train_df, "Train"],
    [test_df, "Test"]
)
comparison.show_notebook()
```
