rsgl - An Implementation of the 'SGL' Graphics Language

Generates plots from a database connection and a 'SGL' statement. 'SGL' is a graphics language designed to look and feel like 'SQL'. It is especially useful for those familiar with 'SQL' who want to specify plots in a similar manner. The 'SGL' language is described in Chapman (2025) <doi:10.48550/arXiv.2505.14690>.
