  Interactive Exploration of Implicit and Explicit Relations in Faceted Datasets

  From financial statistics to nutritional values

  we are frequently exposed to quantitative information expressed in measures of either extreme magnitudes or unfamiliar units

  or both. A common practice used to comprehend such complex measures is to relate

  re-express

  and compare them through visual depictions using magnitudes and units that are easier to grasp. Through this practice

  we create a new graphic composition that we refer to as a concrete scale. To the best of our knowledge

  there are no design guidelines that exist for concrete scales despite their common use in communication

  educational

  and decision-making settings. We attempt to fill this void by introducing a novel framework that would serve as a practical guide for their analysis and design. Informed by a thorough analysis of graphic compositions involving complex measures and an extensive literature review of scale cognition mechanisms

  our framework outlines the design space of various measure relations-specifically relations involving the re-expression of complex measures to more familiar concepts-and their visual representations as graphic compositions.

  Topology-Aware Navigation in Large Networks

  Draco is a sketch-based interface that allows artists and casual users alike to add a rich set of animation effects to their drawings

  seemingly bringing illustrations to life. While previous systems have introduced sketch-based animations for individual objects

  our contribution is a unified framework of motion controls that allows users to seamlessly add coordinated motions to object collections. We propose a framework built around kinetic textures

  which provide continuous animation effects while preserving the unique timeless nature of still illustrations. This enables many dynamic effects difficult or not possible with previous sketch-based tools

  such as a school of fish swimming

  tree leaves blowing in the wind

  or water rippling in a pond. A user study with professional animators and casual users demonstrates the variety of animations

  applications and creative possibilities our tool provides.
