Course duration: 1 day

This course covers all you need to know to explore data visually and create report-ready visualisations using the matplotlib and seaborn libraries.

By attending this course, you will:

  • Learn how to create highly customised plots using both pyplot and object-oriented interfaces in matplotlib, as well as seaborn’s additional plotting facilities.
  • Gain a range of techniques to uncover business insight from your data using different visualisation strategies.
  • Understand the interactions between matplotlib and seaborn to write efficient code for stunning visualisations.

Who is it for?

This course is designed for people with prior knowledge of Python who wish to learn how to use the matplotlib and seaborn libraries to create visualisations for data exploration and business reports.

Prerequisites
