Description

This is a syntax tree of a program, attributed with types. The syntax tree nodes are black, connected by red edges of class 2, and the type attributes are white, connected by blue edges of class 1. These edges are near edges. The layout algorithm tree is selected.

The tree can be visualized with orthogonal edges or with normal edges . The attributes can be made unvisible by the operation Hide edge class 1. Select here to see the result. Subtrees can be folded if they are currently not of interest. Red triangles appear instead of the subtrees. Select here to see the result.
