Colour beads visual representation of compositional relational programs

Building on a compositional relational programming language Combilog, code visualization with a motivation of flexible practical applications is explored. Following from earlier work, a new coloured and human perception-centric iteration of visual representation is introduced, and its effects on understanding code are analysed by means of a user study. Results showed that visuals helped participants to solve code-related questions 46% faster with 69% less errors.
