I was told by a JD Long at a recent conference where I brought up Code2Flow that Mermaid could be used just like Code2Flow within R/Github/etc to draw flowcharts, but it also has other functions that makes it a more generally useful program. Thanks James!

Mermaid is also accessible within R Studio so I can try it here.

In R Studio, DiagrammeR would be the package to install for producing Mermaid graphics.

library(DiagrammeR)

## Warning: package 'DiagrammeR' was built under R version 4.2.3

mermaid("
graph LR
    A-->B
    ")

#Gantt Chart

mermaid("
gantt
    title A Gantt Diagram
    dateFormat  YYYY-MM-DD
    section Section
    A task           :a1, 2014-01-01, 30d
    Another task     :after a1  , 20d
    section Another
    Task in sec      :2014-01-12  , 12d
    another task      : 24d",
    height = '100%', width = '100%'
)

#Flowchart but called Graph in the R package.

mermaid("

graph TD
    A[Christmas] -->|Get money| B(Go shopping)
    B --> C{Let me think}
    C -->|One| D[Laptop]
    C -->|Two| E[iPhone]
    C -->|Three| F[fa:fa-car Car]"
)
