**Release Tag** - [pd.0.0.1](https://github.com/datacommonsorg/api-python/releases/tag/pd0.0.1)
**Release Status** - Current head of branch [`master`](https://github.com/datacommonsorg/api-python/tree/master)
Added pandas wrapper functions.
- `build_time_series` constructs a pd.Series for a given StatisticalVariable and Place, where the time series are indexed by date.
- `build_time_series_dataframe` constructs a pd.DataFrame for a given StatisticalVariable and a set of Places. The DataFrame will have Places as the index and dates as the columns.
- `build_multivariate_dataframe` constructs a pd.DataFrame for a set of StatisticalVariables and a set of Places. The DataFrame will have Places as index and StatisticalVariables as the columns. The values are the most recent values for the chosen StatVarObservation options.
For multi-place functions, when a StatisticalVariable has multiple StatVarObservation options,
Data Commons chooses a set of StatVarObservation options that covers the most places. This
ensures that the data fetched for a StatisticalVariable is comparable across places.
When there is a tie, we select the StatVarObservation options set with the latest date
data is available for any place.
