  - `aggregation_type`: Type of aggregation ("sum", "avg", "count", "max", "min")
  - `verbose`: Optional boolean to display progress messages


---

### `get_timeseries_fields()`
Returns a list of available fields from the timeseries table.

---

### `get_timeseries(gdf, spatial_join_method, fields, start_date=None, end_date=None)`
Gets timeseries data for areas of interest.
- **Parameters:**
  - `gdf`: GeoDataFrame containing areas of interest
  - `spatial_join_method`: "touches", "centroid", or "within"
  - `fields`: List of field names to retrieve
  - `start_date`: Optional start date (format: 'YYYY-MM-DD')
  - `end_date`: Optional end date (format: 'YYYY-MM-DD')
  - `geometry`: Optional "polygon" or "point" to include H3 geometries
  - `verbose`: Optional boolean to display progress messages

---

### `get_timeseries_by_hexids(hex_ids, fields, start_date=None, end_date=None)`
Gets timeseries data for specific H3 hexagon IDs.
- **Parameters:**
  - `hex_ids`: List of H3 hexagon IDs to query
  - `fields`: List of field names to retrieve
  - `start_date`: Optional start date (format: 'YYYY-MM-DD')
  - `end_date`: Optional end date (format: 'YYYY-MM-DD')
  - `geometry`: Optional "polygon" or "point" to include H3 geometries
  - `verbose`: Optional boolean to display progress messages

## Interactive Widgets

Space2Stats provides interactive widgets that make it easy to explore and select data fields in Jupyter notebooks.

### CrossSectionFieldSelector

This widget helps users interactively select fields from the Space2Stats API for cross-sectional data. Fields are organized by their source STAC items for easier navigation.

```python
from space2stats_client import Space2StatsClient, CrossSectionFieldSelector

# Initialize the client
client = Space2StatsClient()

# Create the field selector widget
selector = CrossSectionFieldSelector(client)

# Display the interactive widget in your notebook
selector.display()

# Later, retrieve the selected fields
selected_fields = selector.get_selected_fields()

# Use the selected fields in an API call
gdf = gpd.read_file("path/to/your/area.geojson")
summary = client.get_summary(
    gdf=gdf,
    spatial_join_method="centroid",
    fields=selected_fields
)
```

### TimeSeriesFieldSelector

This widget allows users to interactively select fields for time series data and specify a valid time period based on the available data range.

```python
from space2stats_client import Space2StatsClient, TimeSeriesFieldSelector

# Initialize the client
client = Space2StatsClient()

# Create the time series field selector widget
ts_selector = TimeSeriesFieldSelector(client)

# Display the interactive widget in your notebook
ts_selector.display()

# Later, retrieve the selected fields and time period
selections = ts_selector.get_selections()

# Use the selections in a time series API call
gdf = gpd.read_file("path/to/your/area.geojson")
timeseries_data = client.get_timeseries(
    gdf=gdf,
    spatial_join_method="centroid",
    fields=selections['fields'],
    start_date=selections['time_period']['start_date'].strftime('%Y-%m-%d'),
    end_date=selections['time_period']['end_date'].strftime('%Y-%m-%d')
)
```

## Quick Start

```bash
pip install space2stats-client
```

```python
from space2stats_client import Space2StatsClient
import geopandas as gpd

# Initialize the client
client = Space2StatsClient()

# Get available topics/datasets
topics = client.get_topics()
print(topics)

<<<<<<< HEAD
# Get fields for all datasets
=======
# Get fields for a specific dataset
>>>>>>> main
fields = client.get_fields()
print(fields)

# Get data for an area of interest
gdf = gpd.read_file("path/to/your/area.geojson")
summary = client.get_summary(
    gdf=gdf,
    spatial_join_method="centroid",  # Options: "touches", "centroid", "within"
    fields=["population", "gdp"],
    geometry="polygon"  # Optional: "polygon" or "point"
)

# Get aggregated statistics
aggregates = client.get_aggregate(
    gdf=gdf,
    spatial_join_method="centroid",  # Options: "touches", "centroid", "within"
    fields=["population", "gdp"],
    aggregation_type="sum"  # Options: "sum", "avg", "count", "max", "min"
)

# Get timeseries data
timeseries = client.get_timeseries(
    gdf=gdf,
    spatial_join_method="centroid",
    fields=["spi"],
    start_date="2020-01-01",  # Optional
    end_date="2020-12-31",    # Optional
    geometry="polygon"         # Optional
)

# Get time series data
timeseries = client.get_timeseries(
    gdf=gdf,
    spatial_join_method="centroid",
    fields=["spi"],
    start_date="2020-01-01",
    end_date="2020-12-31"
)
```
