Fixed-Parameter Algorithms for Computing RAC Drawings of Graphs
In a right-angle crossing (RAC) drawing of a graph, each edge is represented
as a polyline and edge crossings must occur at an angle of exactly ,
where the number of bends on such polylines is typically restricted in some
way. While structural and topological properties of RAC drawings have been the
focus of extensive research, little was known about the boundaries of
tractability for computing such drawings. In this paper, we initiate the study
of RAC drawings from the viewpoint of parameterized complexity. In particular,
we establish that computing a RAC drawing of an input graph with at most
bends (or determining that none exists) is fixed-parameter tractable
parameterized by either the feedback edge number of , or plus the vertex

Storytelling and Visualization: An Extended Survey
Throughout history, storytelling has been an effective way of conveying information and knowledge. In the field of visualization, storytelling is rapidly gaining momentum and evolving cutting-edge techniques that enhance understanding. Many communities have commented on the importance of storytelling in data visualization. Storytellers tend to be integrating complex visualizations into their narratives in growing numbers. In this paper, we present a survey of storytelling literature in visualization and present an overview of the common and important elements in storytelling visualization. We also describe the challenges in this field as well as a novel classification of the literature on storytelling in visualization. Our classification scheme highlights the open and unsolved problems in this field as well as the more mature storytelling sub-fields. The benefits offer a concise overview and a starting point into this rapidly evolving research trend and provide a deeper understanding of this topic
