⚡ Quick Start

Basic Usage

from geodatasim import City

# Create city with automatic data loading
istanbul = City("Istanbul")

print(f"Population: {istanbul.population:,}")
print(f"GDP per capita: ${istanbul.gdp_per_capita:,.2f}")
print(f"Climate: {istanbul.climate_zone} ({istanbul.avg_temperature}°C)")
print(f"HDI: {istanbul.hdi}")

# Find similar cities
similar = istanbul.find_similar(n=5)
for city in similar:
    print(f"  - {city.name}, {city.country}")

🆕 ML Clustering (v0.3.0)

from geodatasim.ml import CityClustering, cluster_cities
from geodatasim.analysis import BatchAnalyzer

# Get data
analyzer = BatchAnalyzer(["Istanbul", "Paris", "Tokyo", "New York"])
df = analyzer.to_dataframe()

# Cluster cities
clustering = CityClustering(n_clusters=3, method='kmeans')
clustering.fit(df)

print(f"Silhouette score: {clustering.silhouette_score_:.3f}")
summary = clustering.get_cluster_summary(df)
print(summary)

🆕 Interactive Visualization (v0.3.0)

from geodatasim.viz import CityVisualizer

viz = CityVisualizer()

# Scatter plot
fig = viz.scatter(df, x='population', y='gdp_per_capita',
                  color='region', size='population')
fig.show()  # Interactive in browser
fig.write_html("cities.html")

# Correlation heatmap
viz.heatmap(df, columns=['population', 'gdp', 'hdi']).show()

# Radar chart comparison
viz.radar(df, metrics=['population', 'gdp', 'hdi'],
          cities=['Istanbul', 'Paris', 'Tokyo']).show()

🆕 Auto-Update Engine (v0.3.0)

from geodatasim import City
from geodatasim.core.updater import UpdateEngine, update_city

engine = UpdateEngine()

# Method 1: Update City object (easiest)
istanbul = City("Istanbul")
updated_data = engine.update(istanbul)
if 'population' in updated_data:
    print(f"Population: {updated_data['population']:,}")
if 'gdp_per_capita' in updated_data:
    print(f"GDP: ${updated_data['gdp_per_capita']:,.2f}")

# Method 2: Update specific fields
pop_result = engine.update_population(istanbul)
if pop_result:
    population, metadata = pop_result
    print(f"Updated population: {population:,}")

gdp_result = engine.update_gdp(istanbul)
if gdp_result:
    gdp, metadata = gdp_result
    print(f"Updated GDP: ${gdp:,.2f}")

# Method 3: Update with city data dictionary
city_data = {
    'name': 'Istanbul',
    'country_code': 'TUR',
    'latitude': 41.0082,
    'longitude': 28.9784
}
updated = engine.update_city_all(city_data)

# Method 4: Convenience function
from geodatasim.core.updater import update_city
updated = update_city(istanbul)

# Check if update needed (30-day interval)
needs_update = engine.should_update('Istanbul', 'population')
if needs_update:
    print("Update available!")
