c4r

c4r provides a simple R interface for creating C4 architecture diagrams. The package focuses on the first three levels of the C4 model (Context, Container, Component), generating diagrams using Graphviz DOT notation rendered through {DiagrammeR}. For the Code level, consider the {flow} package.

Installation

c4r is not yet available on CRAN. You can install the development version from GitHub:

# install.packages("pak")
pak::pak("fabiandistler/c4r")

Quick Example 

library(c4r)

# Create a simple system context diagram
c4_context(
  title = "My System Context",
  person = list(c4_person("user", "User", "System user")),
  system = list(c4_system("app", "My App", "Does something useful")),
  relationships = list(c4_rel("user", "app", "Uses"))
)
