When you are talking about data analysis, don’t forget data visualization! It is a very important part of data analysis that can reveal hidden trends and provide more insight into the data. Data visualization can provide information just by looking at them whereas it would take much more time to obtain that same information from spreadsheets or text reports. And that is why Data Visualization is so popular. And in this article, we will discuss the Top R Libraries for Data Visualization.
Since R is one of the most popular programming languages in data analysis, it’s not a shock that there are many R libraries for data visualization. These libraries are so popular because they allow data analysts to create the visualizations they want from their data easily by conveniently providing both the interface and the tools all in one place! Then the only important thing is knowing what the visualization wants to convey to the users and creating that using all the tools available. What more could a data analyst want?!
So let’s check out some of these Top R Libraries for Data Visualization that are commonly used these days.
ggplot2 is an R data visualization library that is based on The Grammar of Graphics. ggplot2 can create data visualizations such as bar charts, pie charts, histograms, scatterplots, error charts, etc. using high-level API. It also allows you to add different types of data visualization components or layers in a single visualization. Once ggplot2 has been told which variables to map to which aesthetics in the plot, it does the rest of the work so that the user can focus on interpreting the visualizations and take less time in creating them. But this also means that it is not possible to create highly customized graphics in ggplot2. But there are a lot of resources in the RStudio community and Stack Overflow which can provide help in ggplot2 when needed. Just like dplyr, if you want to install ggplot2, you can install the tidyverse or you can just install ggplot2 using install.packages(“ggplot2”)
Esquisse is a data visualization tool in R that allows you to create detailed data visualizations using the ggplot2 package. You can create all sorts of scatter plots, histograms, line charts, bar charts, pie charts, error bars, box plots, multiple axes, sparklines, dendrograms, 3-D charts, etc. using Esquisse and also export these graphs or access the code for creating these graphs. Esquisse is such a famous and easily used data visualization tool because of its drag and drops ability that makes it popular even among beginners. You can install Esquisse from CRAN using install.packages(“esquisse”) or install the development version from GitHub using remotes::install_github(“dreamRs/esquisse”).
Lattice is a data visualization tool that is primarily used to implement Trellis graphs in R. These Trellis graphs are used to view many complicated and multi-variable data sets at the same time so they can be compared. Since all these different plots end up looking like a Trellis, this is called a Trellis graph. Since Lattice is a high-level data visualization library, it can handle many of the typical graphics without needing many customizations. In case you want to extend the capabilities of Lattice, they can download the LatticeExtra package which is an extended version. You can install Lattice from CRAN using install.packages(“lattice”) or install the development version from GitHub using remotes::install_github(“deepayan/lattice”).
The RGL package in R is created specifically for making 3-D data visualizations and data plots. It has many graphics commands that work in 3 dimensions but is modeled loosely after the classic 2-D graphics in R. RGL is also inspired by the grid package in R but it is incompatible with it. However, seasoned R coders can easily use RGL because of an existing familiarity with the grid. And RGL is very cool! It has a lot of options for 3-D shapes, various lighting effects, creating new shapes, and also animations. You can install RGL from CRAN using install.packages(“rgl”).
All of these R Libraries for Data Visualization are excellent options if you want to create data visualizations. Each of these libraries has its strengths and you can choose the best one depending on the type of visualization or data science project you want to create. Now that you know these libraries, go on and create beautiful yet informative data visualizations using them!
