Python Connector Libraries for Google Drive Data Connectivity. Integrate Google Drive with popular Python tools like Pandas, SQLAlchemy, Dash & petl.

How to Visualize Google Drive Data in Python with pandas

Use pandas and other modules to analyze and visualize live Google Drive data in Python.

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData Python Connector for Google Drive, the pandas & Matplotlib modules, and the SQLAlchemy toolkit, you can build Google Drive-connected Python applications and scripts for visualizing Google Drive data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to Google Drive data, execute queries, and visualize the results.

With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live Google Drive data in Python. When you issue complex SQL queries from Google Drive, the driver pushes supported SQL operations, like filters and aggregations, directly to Google Drive and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to Google Drive Data

Connecting to Google Drive data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.

You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

Follow the procedure below to install the required modules and start accessing Google Drive through Python objects.

Install Required Modules

Use the pip utility to install the pandas & Matplotlib modules and the SQLAlchemy toolkit:

pip install pandas
pip install matplotlib
pip install sqlalchemy

Be sure to import the module with the following:

import pandas
import matplotlib.pyplot as plt
from sqlalchemy import create_engine

Visualize Google Drive Data in Python

You can now connect with a connection string. Use the create_engine function to create an Engine for working with Google Drive data.

engine = create_engine("googledrive:///?InitiateOAuth=GETANDREFRESH&OAuthSettingsLocation=/PATH/TO/OAuthSettings.txt")

Execute SQL to Google Drive

Use the read_sql function from pandas to execute any SQL statement and store the resultset in a DataFrame.

df = pandas.read_sql("SELECT Name, Size FROM Files WHERE Starred = 'true'", engine)

Visualize Google Drive Data

With the query results stored in a DataFrame, use the plot function to build a chart to display the Google Drive data. The show method displays the chart in a new window.

df.plot(kind="bar", x="Name", y="Size")
