Data Analysis and Visualization with Python

Data analysis and data visualization are essential skills for data professionals. With the demand for data professionals expected to increase by nearly 30% in the next five years, it is important to start developing new skills you can implement in your career. Python offers some great tools for analyzing data and creating different kinds of visuals to recognize patterns in data and create insights.

In this skill path, we'll introduce you to popular open-source Python libraries for data analysis. Additionally, you’ll learn the fundamentals of data visualization in Python by exploring graph interpretation (statistics) and tooling (Matplotlib and seaborn).

  • Discover powerful libraries like pandas and NumPy for data analysis
  • Create and update dictionaries, create custom functions, and use Jupyter Notebook
  • Build intermediate-level skills like cleaning, correcting, and preparing data for analysis
