Data visualization plays a vital role in life even for an HR Analytics professional.
It is easier to visualize complex data and relationships than deciphering them from spreadsheets/tables.
There are several tools for visualizing data such as Tableau, Qlik, Dygraphs, Kibana etc. If I talk specifically about R, it provides three plotting systems:
The Base Plotting System.
The Lattice System.
The ggplot2 System.
But, writing codes for plotting graphs in R time & again can get very tiring. Also, it is very difficult to create an interactive visualization for story narration using the above packages. These problems can be resolved by dynamically creating interactive plots in R using Shiny with minimal effort.
