Omnicode: A Novice-Oriented Live Programming Environment with Always-On Run-Time Value ...
summary
Omnicode builds a live Python IDE that continually runs code and visualizes the entire history of every numerical value in an always-on scatterplot matrix with derived metrics for lists/dicts, custom Python expressions, and system axes like line number. Code selection filters marks and brushing highlights corresponding lines; zoom reveals stack/heap at a step. A 10-participant study (75-minute sessions, three list-focused tasks) finds improvements in debugging, mental models and serendipitous discoveries (e.g., copy-by-reference, integer vs float division) but notes visual overload as the main limitation. brush-and-link selection
