The construction and evaluation of code may be conducted entirely in a graphical view or with a combination of textual and visual tools. Code constructed visually may be viewed textually, or vice versa. Objects appear as rounded corner rectangles with a textual label. Messages appear in a rectangle below the objects to which they are sent. Directed connections represent the flow of objects.
Statements are tree-like structures within a block.
