Data Visualization with Python

With so much data being continuously generated, developers with a knowledge of data analytics and data visualisation are always in demand. In this Data Visualisation with Python course, you'll learn how to use Python with NumPy, Pandas, Matplotlib, and Seaborn to create impactful data visualisations with real world, public data.

Key Features of this Data Visualisation with Python Training:

  • After-course instructor coaching benefit
  • After-course exam included

Who Should Attend

Data Visualisation with Python is designed for developers and scientists, who want to get into data science or want to use data visualisations to enrich their personal and professional projects. You do not need any prior experience in data analytics and visualisation, however, it'll help you to have some knowledge of Python and familiarity with high school level mathematics. Even though this is a beginner level course on data visualisation, experienced developers will be able to improve their Python skills by working with real-world data.
