How to Visualize Apify Data in Python with pandas

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

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

Connecting to Apify Data

Connecting to Apify 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.

Start by setting the Profile connection property to the location of the Apify Profile on disk (e.g. C:\profiles\Apify.apip). Next, set the ProfileSettings connection property to the connection string for Apify (see below).

Apify API Profile Settings

Obtain your API token from the Apify Console by navigating to Settings and generating a new API token.

Follow the procedure below to install the required modules and start accessing Apify 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 Apify Data in Python

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

engine = create_engine("api:///?Profile=C:\profiles\Apify.apip&ProfileSettings='APIKey=your_api_token'")

Execute SQL to Apify

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

df = pandas.read_sql("SELECT Id, ActorId FROM ActorBuilds WHERE Status = 'SUCCEEDED'", engine)

Visualize Apify Data

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

df.plot(kind="bar", x="Id", y="ActorId")
plt.show()
