Honorable Mention
Documentation in codebases facilitates knowledge transfer. But tools for programming are largely text-based, and so developers resort to creating ASCII diagrams---graphical artifacts approximated with text---to show visual ideas within their code. Despite real-world use, little is known about these diagrams. We interviewed nine authors of ASCII diagrams, learning why they use ASCII and what roles the diagrams play. We also compile and analyze a corpus of 507 ASCII diagrams from four open source projects, deriving a design space with seven dimensions that classify what these diagrams show, how they show it, and ways they connect to code. These investigations reveal that ASCII diagrams are professional artifacts used across many steps in the development lifecycle, diverse in role and content, and used because they visualize ideas within the variety of programming tools in use. Our findings highlight the importance of visualization within code and lay a foundation for future programming tools that tightly couple text and graphics.
