Create visual representations of data that models real-world phenomena or processes : Matplotlib library

The video tutorial covers the basics of data visualization using the Matplotlib library in Python. It begins with an introduction to the importance of data visualization in data science, followed by a step-by-step guide on installing Matplotlib. The tutorial then demonstrates how to create a simple line chart with GDP data, including setting up the Python script and handling potential errors during execution. The video concludes with a brief mention of future topics, such as bar charts and scatter plots.

What is the primary purpose of the Matplotlib library in Python?

• To perform complex mathematical calculations

• Import the pyplot module

• Define the data arrays

• Install Python

Which alias is commonly used for the pyplot module in Matplotlib?

• graph

• plot

• py

• plt

What parameter is used to set the color of a line in a Matplotlib plot?

• tint

• shade

• hue

• color

If a line style error occurs, what is a possible solution?

• Update the Python version
