    <epdcx:statement epdcx:propertyURI="http://purl.org/dc/elements/dc/terms/abstract">
      <epdcx:valueString>In this paper we provide upper and lower bounds on the area requirement of straight-line orthogonal drawings of $n$-node binary and ternary trees. Namely, we show algorithms for constructing order-preserving straight-line orthogonal drawings of binary trees in $O(n^1.5)$ area, straight-line orthogonal drawings of ternary trees in $O(n^1.631)$ area, and straight-line orthogonal drawings of complete ternary trees in $O(n^1.262)$ area. As far as we know, the ones we present are the first algorithms achieving sub-quadratic area for these problems. Further, for upward order-preserving straight-line orthogonal drawings of binary trees and for order-preserving straight-line orthogonal drawings of ternary trees we provide $Omega(n^2)$ area lower bounds, that we also prove to be tight.</epdcx:valueString>
