## Data Visualization with R

The key objective of any data science project is to use automated methods to analyze massive amounts of data and to extract knowledge from it. This puts data visualization at the forefront of any data science project.

You will learn about various types of charts and tables to present the data in a quick, understandable and meaningful way.

You we also will learn about how to create data visualizations using base graphics ggplot2 in R.
