We present the results of a user study that compares different ways of representing Dual-Scale data charts. Dual-Scale charts incorporate two different data resolutions into one chart in order to emphasize data in regions of interest or to enable the comparison of data from distant regions. While some design guidelines exist for these types of charts, there is currently little empirical evidence on which to base their design. We fill this gap by discussing the design space of Dual-Scale… 
TimeNotes: A Study on Effective Chart Visualization and Interaction Techniques for Time-Series Data
TLDR
This paper comparatively evaluates existing methods, such as Stack Zoom and ChronoLenses, giving a graphical overview of each and classifying their ability to explore and interact with data, and proposes new visualizations and other extensions to the existing approaches.
Lin-spiration: using a mixture of spiral and linear visualization layouts to explore time series
TLDR
A novel interactive visualization paradigm for exploring and comparing multiple sets of time series data is proposed, where a "focus" segment of a time series is zoomed into and visualized using a linear layout at one scale, while the remaining segments of the time series are visualization using spiral data layouts.
Composite Visual Mapping for Time Series Visualization
TLDR
This work investigates composite visual mapping: mapping single data attributes onto several visual channels, each one representing one aspect of the data attribute, and expects that using more than one visual channel for communicating a data attribute increases the bandwidth of information presentation by displaying separable information on different aspects of data.
The Impact of Shape on the Perception of Euler Diagrams
TLDR
It is established that curve shape does indeed impact on understandability of an Euler diagram, and it is concluded that, where possible, circles should be used to draw effective Euler diagrams.
Order of Magnitude Markers: An Empirical Study on Large Magnitude Number Detection
TLDR
The motivation for this work is that many data sets require the depiction and comparison of numbers that have varying orders of magnitude, and existing techniques for representation use bar charts, plots and colour on linear or logarithmic scales, which all suffer from related problems.
Perception of Visual Variables on Tiled Wall-Sized Displays for Information Visualization Applications
TLDR
An understanding of, and indicators predicting how, large variations in viewing distances and viewing angles affect the accurate perception of angles, areas, and lengths is contributing to design considerations on how to create effective visualizations for these spaces.
Interactive horizon graphs: improving the compact visualization of multiple time series
TLDR
The results show that IHG outperform the other two techniques in complex comparison and matching tasks where the number of charts is large, and in the hardest task PHG have a significantly higher number of good answers than HG and RLC and a lower error magnitude.
The Effects of Length and Orientation on Numerical Representation in Flow Maps
TLDR
This study performs a user study to determine the effect of length and orientation on thickness perception and provides some concrete guidelines for the design of flow maps that may be beneficial to map designers.
An Empirical Study of Task-Specific Limitations of the Overview+Detail Technique for Interactive Time Series Analysis
TLDR
Potential usability issues of O+D for typical time series analysis tasks are identified and alternative interaction and visualisation designs or other strategies to maintain good usability are proposed, even for challenging task types and data densities.
Evaluating the Impact of Clutter in Linear Diagrams
TLDR
It is concluded that clutter affects the interpretation oflinear diagrams, and methods for controlling the level of clutter in linear diagrams, such as using multiple diagrams instead of a single diagram, when visualizing sets are established.

Graphical Perception: Theory, Experimentation, and Application to the Development of Graphical Methods
Abstract The subject of graphical methods for data analysis and for data presentation needs a scientific foundation. In this article we take a few steps in the direction of establishing such a
A Space of Presentation Emphasis Techniques for Visualizing Graphs
TLDR
This paper describes an abstract space of presentation emphasis techniques, and locate the current approaches within this space, and proposes a common set of criteria and a taxonomy of graph views.
Stack zooming for multi-focus interaction in time-series data visualization
TLDR
A method for supporting this kind of multi-focus interaction that is based on the user interactively building hierarchies of 1D strips stacked on top of each other, where each subsequent stack represents a higher zoom level, and sibling strips represent branches in the visual exploration.
A framework for unifying presentation space
TLDR
A unified framework is presented that provides a way of relating seemingly distinct methods, facilitating the inclusion of more than one presentation method in a single interface, and supports extrapolation between the presentation methods it describes.
Useful junk?: the effects of visual embellishment on comprehension and memorability of charts
TLDR
It is found that people's accuracy in describing the embellished charts was no worse than for plain charts, and that their recall after a two-to-three-week gap was significantly better, questioning some of the premises of the minimalist approach to chart design.
A framework for elastic presentation space
TLDR
The research into the presentation problem has led to the development of a framework that describes a presentation space in which the adjustments and reorganizations are elastic in the sense that reverting to previous presentations is facilitated, and this framework provides a way of relating seemingly distinct methods.
On the effects of viewing cues in comprehending distortions
TLDR
A study about relative difficulty in reading distortions that investigates the effect of the use of viewing cues such as the cartographic grid and shading on people's ability to interpret distortions.
A review of overview+detail, zooming, and focus+context interfaces
TLDR
The aim is to provide a succinct summary of the state-of-the-art interface schemes, to illuminate both successful and unsuccessful interface strategies, and to identify potentially fruitful areas for further work.
The perspective wall: detail and context smoothly integrated
TLDR
This paper describes a technique called the Perspective W’aU for visualizing linear information by smoothly integrating detailed and contextual views that fold wide 2D layouts into intuitive 3D visualizations that have a center panel for detail and two perspective panels for context.
Perception of elementary graphical elements in tabletop and multi-surface environments
TLDR
It is found that the perception of some graphical elements is more robust to distortion than others and recommendations for building data visualizations for use in a tabletop and multi-display environment are developed.
