The techniques and systems described herein provide a tool for use in association with the development of a computer program. For instance, a computer program development team (e.g., design architects, developers, programmers, coders, etc.) can use the tool to efficiently generate code solutions using an illustrated diagram (e.g., drawn on a dry-erase white board, drawn using a digital drawing program, etc.). In various examples, the tool receives a diagram illustrating the design architecture and performs recognition techniques to identify characteristics of the components illustrated in the diagram. The characteristics can include keywords written on or in association with a component, a visual shape of a component, and a visual relationship between the component and other components illustrated in the design architecture. Using the identified characteristics, the tool maps the components to previously generated code template(s) and provides the code templates to a user.
