This course will help learners take data visualization skills beyond the basics and hone them into a powerful member of your data science toolkit. Over the lessons, we will use two interesting open datasets to cover different types of data (proportions, point-data, single distributions, and multiple distributions) and discuss the pros and cons of the most common visualizations. In addition, we will cover some less common alternatives visualizations for the data types and how to tweak default ggplot settings to most efficiently and effectively get the message across.
