This book (https://smin95.github.io/dataviz) guides the reader to be familiar with R, a programming language, for data visualization. It also introduces the R package smplot2, which aims to make the process of data visualization simple. This book was created entirely using RMarkdown for reproducibility. The secondary link of the e-book is: https://smin95.com/dataviz.

The old website (on smplot) can be accessed using this link (https://smin95.com/dataviz0).
