Upward drawing is a widely studied drawing convention for the visual representation of directed graphs. In an upward drawing vertices are mapped to distinct points of the plane, and edges are curves monotonically increasing in the vertical direction, according to their orientation. In particular, not all planar digraphs admit an upward planar drawing (i.e., an upward drawing with no edge crossing),...
We extend the recently introduced slanted-orthogonal (for short: slog) drawing model to a new relaxed model that we call sloggy, which allows crossings not exclusively on diagonals but also on rectilinear edge segments. Because of that, sloggy drawings might require much less bends than the corresponding drawings in the slog drawing model. On the positive side, we prove a closed-form formula on the...
