%description
An 'R' interface to 'pikchr' (<https://pikchr.org>, pronounced “picture”),
a 'PIC'-like markup language for creating diagrams within technical
documentation. Originally developed by Brian Kernighan, 'PIC' has been
adapted into 'pikchr' by D. Richard Hipp, the creator of 'SQLite'.
'pikchr' is designed to be embedded in fenced code blocks of Markdown or
other documentation markup languages, making it ideal for generating
diagrams in text-based formats. This package allows R users to seamlessly
integrate the descriptive syntax of 'pikchr' for diagram creation directly
within the 'R' environment.
