Summary: A layered drawing of a tree $$T$$ is a planar straight-line drawing of $$T$$, where the vertices of $$T$$ are placed on some horizontal lines called layers. A minimum-layer drawing of $$T$$ is a layered drawing of $$T$$ on $$k$$ layers, where $$k$$ is the minimum number of layers required for any layered drawing of $$T$$. In this paper we give a linear-time algorithm for obtaining minimum-layer drawings of trees.
