R is a programming language and software environment designed primarily for statistical computing and graphics. It belongs to the code-based route to visualization, where writing code provides precise control over how visualizations look and behave. section 1.5.3
A practical code-first workflow:
- Start with an existing library when it provides the needed functionality; write custom functions, classes, or objects only when necessary. section 1.5.3
- Expect more technical work than spreadsheet or business-intelligence tools require, but gain finer control over the final visualization. section 1.5.3
