We describe a visualization method for general logic clauses as the first step of a visualization of logic programs. Since we think inclusion is essential to represent an outline of knowledge, we propose a method based on Euler diagrams to visualize inference rules represented as a set of general logic clauses which consist of literals with no variable. We develop a prototype system and show that complex rules which are hard to understand in text are easy to understand by diagrams.
