Flowcharts with 'ggplot2'.
{ggflowchart}
{ggflowchart} is an R package for producing flowcharts using {ggplot2}.
Installation
Install the package from CRAN using:
install.packages("ggflowchart")
or install the development version from GitHub:
remotes::install_github("nrennie/ggflowchart")
Usage
The idea of {ggflowchart} is to create simple flowcharts with minimal effort. Currently, all flowcharts are constructed using the ggflowchart()
function. For the most basic flowchart, it takes as input a data frame containing (at least) two columns for the start and end points of the edges in the flowchart.
data <- tibble::tibble(from = c("A", "A", "A", "B", "C", "F"),
to = c("B", "C", "D", "E", "F", "G"))
The flowchart is then created using ggflowchart()
.
ggflowchart(data)
See vignettes for further examples of usage.
Upcoming features

- Changing node outline
colour
based on node attributes. - Changing
linetype
andcolour
of arrows based on edge attributes. - Same-level arrows (currently an issue with crossing over).
