'''ggplot2''' is an [[open-source]] [[data visualization]] [[R package|package]] for the [[Computational statistics|statistical programming]] language [[R (programming language)|R]]. Created by [[Hadley Wickham]] in 2005, ggplot2 is an implementation of [[Leland Wilkinson]]'s ''[[Wilkinson's Grammar of Graphics|Grammar of Graphics]]''—a general scheme for data visualization which breaks up graphs into semantic components such as scales and layers. ggplot2 can serve as a replacement for the base graphics in R and contains a number of defaults for web and print display of common scales. Since 2005, ggplot2 has grown in use to become one of the most popular R packages.<ref>{{cite journal|last=Wickham|first=Hadley|title=ggplot2: Elegant Graphics for Data Analysis|journal=Journal of Statistical Software|date=July 2010|volume=35|issue=1|url=http://www.jstatsoft.org/v35/b01/paper}}</ref><ref>{{cite journal|last=Wilkinson|first=Leland|author-link=Leland Wilkinson|title=ggplot2: Elegant Graphics for Data Analysis by WICKHAM, H|journal=Biometrics|date=June 2011|volume=67|issue=2|pages=678–679|doi=10.1111/j.1541-0420.2011.01616.x}}</ref><ref>{{cite web|url=https://cran.r-project.org/web/packages/ggplot2/index.html|title=CRAN - Package ggplot2|date=12 October 2023 }}</ref>
