covizpy 1.0.21

Provides access to Covid-19 data from Our World in Data, and functions to generate relevant charts and summaries.

covizpy

covizpy is a Python package that provides easy access to Covid-19 data from Our World in Data, as well as functions to generate relevant Covid-19 charts and summaries easily. We aim to make covizpy simple and easy to use. Our goal is to enable anyone with basic Python programming knowledge to access and visualize Covid-19 data, and make their own informed decisions and conclusions.

There are existing Python packages that allow users to download and generate Covid-19 charts. For example, covid19pandas is a package that presents COVID-19 data from Johns Hopkins University and The New York Times in pandas dataframes, to make analysis and visualization easier in a Python environment.

While other packages have more advanced plotting capabilities, we provide simpler functions that allow users to answer questions regarding the Covid-19 pandemic as quickly as possible.

Features

This package contains four functions: plot_metric, plot_spec, get_data and plot_summary.

• plot_metric: Create a line chart presenting COVID total new cases versus another metric within a time period

• plot_spec: Create a line chart presenting specific country/countries COVID information within a time period

• get_data: User can retrieve the COVID data from the source as a pandas dataframe. Specific data can be retrieved by passing the date range and the list of countries

• plot_summary: Create a horizontal bar chart summarising a specified variable and value within a time period

Dependencies

Before installing the package, following packages must be installed:

• python = "^3.9"
• pandas = "^1.3.5"
• altair = "^4.2.0"
• altair-saver = "^0.5.0"

Installation

pip install covizpy

Usage and Examples

To use the package, import the package with following commands:

from covizpy.get_data import get_data
from covizpy.plot_summary import plot_summary
from covizpy.plot_metric import plot_metric
from covizpy.plot_spec import plot_spec

To use the functions, see below examples:

Retrieve COVID-19 data with specified date range and default all locations

df = get_data(date_from="2022-01-01", date_to="2022-01-21")

Plot summary graph (bar chart)

plot_summary(df, var="location", val="new_cases", fun="sum", date_from="2022-01-01", date_to="2022-01-15", top_n=10)

Plot COVID-19 cases for specific countries (line chart)

plot_spec(df, location=["Canada", "Turkey"], val="new_cases", date_from="2022-01-01", date_to="2022-01-07")

Plot new COVID-19 cases versus another metric (line chart)

plot_metric(location="Canada", metric="positive_rate", date_from="2022-01-01", date_to="2022-01-15")
