Learn ggplot2 in R for Data Visualization
Learn ggplot2 in R for Data Visualization
Data Visualization is essential for data analysis and data science, so become an expert in ggplot from scratch!
In this course, I’m going to teach you how to use the ggplot2 package of R to draw amazing charts that are able to communicate what your data has to say in the most polished, professional way. My name is Clara and I am a Complex Systems researcher and Data Visualization professor at the University. Currently, ggplot2 is the best, most powerful tool for building professional graphics. First, because this is a package available in R, which is one of the most used programming languages for Data Science and related fields. So, it is very convenient to be able to produce graphics in the same environment where you already do all of your calculations. Second, because it is the most flexible tool to build graphs. So, even if you don’t use R for your analyses, it is worth it to use ggplot2 to draw your plots, because there’s no other tool that will give you the results that you can achieve using ggplot2.
