A visleaf, or a leaf, is a type of volume in a map created by the visibility compile tools. When any part of a leaf is visible from any part of the current leaf, the entire contents of that leaf are considered for rendering.
The console variable "mat_leafvis 1" draws a red wireframe box around the Player's current visleaf, which is redrawn each time a new leaf is entered.
Leaves can also be examined from the desktop with the glview tool.
