Why Learn Data Visualization?
When we present data graphically, we can see the patterns and insights we’re looking for. It becomes easier to grasp difficult concepts or identify new trends we may have missed. We can use data visualizations to make an argument, or to support a hypothesis, or to explore our world in different ways.
Python allows us to create visualizations easily and quickly using Matplotlib and Seaborn.
Take-Away Skills:
Matplotlib is the most commonly used graphing tool in Python. You will learn how to:
- Create line graphs
- Create bar charts
- Create pie graphs
- Add error bars to graphs
- Add labels and styling to graphs
Seaborn is an add-on to Matplotlib that allows us to style our graphs more professionally and create sleeker graphics. You will learn how to choose color schemes for your graphs and take them to the next level.
Notes on Prerequisites:
You should know basic Python, including how to write functions, use lists and loops, and call methods on objects.
