## 💻 Quick Start Guide

### Installation
```bash
pip install datasets pandas geopandas shapely matplotlib
```

### Basic Usage
```python
from datasets import load_dataset
import pandas as pd
import geopandas as gpd
from shapely import wkt

# Load the datasets from Hugging Face Hub
features_ds = load_dataset("alidenewade/nyc-urban-analytics", 
                          split="train", 
                          data_files="nyc_cesium_features.parquet")
tracts_ds = load_dataset("alidenewade/nyc-urban-analytics", 
                        split="train", 
                        data_files="nyc_tracts.parquet")

# Convert to pandas DataFrames
features_df = features_ds.to_pandas()
tracts_df = tracts_ds.to_pandas()

print(f"📊 Panel Data Shape: {features_df.shape}")
print(f"🗺️ Geographic Data Shape: {tracts_df.shape}")
```

## 🗺️ Geospatial Analysis Example

### Prepare Geographic Data
```python
# Convert WKT strings to geometry objects
tracts_df['geometry'] = tracts_df['geometry'].apply(wkt.loads)

# Create GeoDataFrame
tracts_gdf = gpd.GeoDataFrame(tracts_df, geometry='geometry', crs="EPSG:4326")
```

### Crime Hotspot Analysis
```python
# Aggregate crime data for 2023
features_df['month'] = pd.to_datetime(features_df['month'])
crime_2023 = features_df[features_df['month'].dt.year == 2023]
crime_by_tract = crime_2023.groupby('GEOID')['crime_total'].sum().reset_index()

# Merge with geographic data
crime_map = tracts_gdf.merge(crime_by_tract, on='GEOID', how='left').fillna(0)

# Create choropleth map
import matplotlib.pyplot as plt
fig, ax = plt.subplots(figsize=(15, 10))
crime_map.plot(column='crime_total', 
               cmap='viridis', 
               legend=True,
               ax=ax)
ax.set_title('NYC Crime Density by Census Tract (2023)', fontsize=16)
plt.tight_layout()
plt.show()
```

## 📈 Advanced Analysis Examples

### Time Series Analysis
```python
# Analyze crime trends for a specific tract
tract_id = "36061000100"  # Example tract in Manhattan
tract_data = features_df[features_df['GEOID'] == tract_id].copy()
tract_data['month'] = pd.to_datetime(tract_data['month'])
tract_data = tract_data.sort_values('month')

# Plot time series
plt.figure(figsize=(12, 6))
plt.plot(tract_data['month'], tract_data['crime_total'], marker='o')
plt.title(f'Crime Trends - Census Tract {tract_id}')
plt.xlabel('Month')
plt.ylabel('Total Crimes')
plt.xticks(rotation=45)
plt.grid(True, alpha=0.3)
plt.tight_layout()
plt.show()
```

### Service Request Analysis
```python
# Top 311 complaint types correlation with crime
correlation_data = features_df[['crime_total', 'sr311_total']].corr()
print("Crime vs 311 Requests Correlation:")
print(correlation_data)
```
