Interactive Infographics in German Online Newspapers Sandra Zwinger Michael Zeiller University of Applied Sciences Burgenland University of Applied Sciences Burgenland Eisenstadt, Austria Eisenstadt, Austria sandra.zwinger@live.at michael.zeiller@fh-burgenland.at illustrate a point made in a story in a more compelling way, to remove unnecessary technical information from prose and to provide transparency about the reporting Abstract process to readers (especially interactive visualizations Interactive infographics are increasingly used that allow exploration) [GBC12]. in online journalism. Especially in data-driven Information visualization is the use of interactive journalism they provide a powerful tool to visual representations of abstract data to amplify represent and communicate complex cognition [Che10] [War12]. Information visualization in information. On the basis of a content analysis online media like online newspapers or online of five German-speaking online newspapers magazines can be interactive, i.e., it provides users with we show which kinds of interactive at least one option to control which and how much visualizations are preferred in German- information shall be shown. Shneiderman [Shn96] speaking online media. However, users are still proposed key principles for the success of information unfamiliar with interactive infographics. The visualization that are based on his Visual Information- results of a user survey demonstrate how Seeking Mantra: Overview first, zoom and filter, then readers of online newspapers use interactive details-on-demand. Since then several types of infographics. These results point out how users interactivity have emerged. Information visualization interact with interactive infographics and how provides several types of information graphics, e.g., they assess the availability and findability of functional infographics, cartographical graphics or interactive infographics in online newspapers. visualization of statistical data, that can be enhanced with interactive elements. Journalists tell stories based on their investigations. 1. Introduction Data visualization is an appropriate communication Data-driven journalism (short: DDJ) collects, evaluates, medium for storytelling, in particular when the story interprets and presents large amounts of data. In an also contains a lot of data [KM13]. However, these data innovative and unique way data-driven journalism stories told by data journalists differ from traditional explains new insights and clarifies facts while telling forms of storytelling [SH10]. An emerging number of complex stories on the basis of large amounts of stories is enhanced with narratives including complex retrieved data [Mat16] [GBC12]. Lorenz [Lor10] graphics and especially interactive graphics. Like the defines data-driven journalism as a workflow, where pioneers of data-driven journalism using interactive data is the basis for analysis, visualization and – most visualizations from Anglo-Saxon countries (e.g., The importantly – storytelling. The growth potential of data- Guardian, The New York Times) the increasing number driven journalism is vast and according to Weinacht und of data-driven journalistic projects in German-speaking Spiller [WS14] it is one of the big issues in specialist countries use various visualizations with different publications on journalism and in education of options of interaction. journalists in Germany. In this paper, we investigate which kinds of Data-driven journalism can help a journalist to tell a interactive infographics are used in data-driven complex story through engaging information graphics journalism in Germany, Austria and Switzerland to [GBC12] [WR13]. In the reporting phase, visualizations effectively present complex data and causal can help journalists to identify themes and questions, to relationships. A content analysis is applied to five identify outliers or to find typical examples. In examples of German-speaking online newspapers. The publishing, visualizations play multiple roles, e.g., to interactive infographics that have been published in 2014 and 2015 are analyzed. Copyright © by the paper’s authors.

First, readers have to identify Proceedings of the 9th Forum Media Technology 2016, St. Pölten, Austria, 24-11-2016, published at http://ceur-ws.org 54 Interactive Infographics in German Online Newspapers interactive infographics as such and the control tools graphics, structure graphics and process graphics have to be recognized intuitively. Thus, we investigate (Figure 2). [JS99] how readers of online newspapers assess the availability and findability of interactive infographics and which types of interaction they utilize. 2 Interactive Infographics Information graphics (short: infographics) combine graphics, image and text to communicate information, data or knowledge effectively using graphic visual Figure 2: Fact graphics (left) und process graphics representations [Ale13] [Yau11] [Yau13]. Infographics (right) (Source: [JS99]) aim at providing the percipient with new insights and a quick overview on complex facts on subjects like The cartographic infographics (map) conveys space- politics, science, technology, and nature that are hard to oriented information in a clearly arranged, simple and understand just using text-based information. They shall understandable way that provides orientation. This type communicate complex issues efficiently and draw the consists of event space map, topic map and weather attention of percipients to them. However, there is a map. [JS99] continuous debate over visual embellishment, i.e., Statistics charts help to illustrate quantities and adding unnecessary visual embellishment – chart junk – compare them, especially large, complex sets of versus a minimalistic approach using plain and simple numbers and relations. This type consists of pie chart, charts [BMG+10]. Like the data-ink ratio for bar chart, curve chart, area diagram, scatter plot, Sankey noninteractive infographics proposed by Tufte [Tuf01] diagram and radar chart (Figure 3). [JS99] [Sta13] to reduce chart junk, interactive infographics have to apply interactivity purposeful. 2.1 Types of Infographics Infographics can be categorized in three basic types (Figure 1): [JS99] [Sta13] • Principle representation • Cartographic infographics • Statistics chart Figure 3: Bubble graph (scatter plot, left, Source: www.nytimes.com) and Sankey diagram (right, Source: www.ensbirasjon.blogspot.dk) 2.2 Interactions in Infographics Many technical systems offer interactive performance. However, the interactive elements have to be recognized and utilized by users. This level of action is made up of a control dimension and a transmission dimension that allows the system to react on user input. The control dimension ist subdivided in options for selection (selection of existing content, e.g., click on a hyperlink) Figure 1: Three types of infographics (Source: [JS99]) and options for modification (change of system range by input; e.g., input of text) [QS06]. The principle representation – also denoted as functional There exist several methods of interaction to graphics – covers What and How questions and manipulate a visual representation, like scrolling, describes complex causal relationships in real or abstract form. Principle representations are subdivided in fact 55 Interactive Infographics in German Online Newspapers overview plus detail, or focus plus context, filtering or data reordering [Maz09]. Weber and Wenzel [WW13] define interactive infographics as being a visual representation of information that integrates several modes (at least two), e.g., image/video, spoken or written text, audio, layout, etc. (image mode is constitutive), to a coherent ensemble that offers at least one option of control to the user. The provided option of control can be, e.g., • Start or Stop button • Forward or backward button • Menu item to select • Timeline or time controller • Filter, data request or input box 2.3 Classification of Interactive Infographics Figure 4: Infographics showing German House of While evaluating interactive infographics we analyze Parliament with high interactivity five features which cover interaction as well as narrative (Source: www.spiegel.de, [WW13]) issues: degreee of interactivity, course of action, communicative intent, “W-questions” and topic. We 2.3.2 Course of Action follow a typology introduced by Weber and Wenzel Weber and Wenzel [Web13] [WW13] distinguish three [WW13] and Weber [Web13]. Other features like genre types of course of action: or visual narrative as in [SH10] might be applied as well, but have not been included. • Linear • Nonlinear 2.3.1 Degree of Interactivity • Linear-nonlinear Weber and Wenzel [WW13] distinguish three degrees Linear interactivity enables the user to move (forward or of interactivity: backward) through a predetermined linear sequence • Low interactivity [Sim97]. The linear type is based on a step-by-step • Medium interactivity course defined by the author (i.e., author-driven • High interactivity [SH10]). The user follows a strict path and does not have to explore the visualization by himself. Navigation tools A low level of interactivity allows users to navigate like Start, Stop, Forward, Backward or Next are used to within the infographics and select content, e.g., by using navigate in a liner course. A navigation bar provides a internal links, zooming, mouseover effects for showing better overview on the whole sequence.

On a medium level of interactivity users prescribed ordering and requires a high degree of can manipulate the infographics, e.g., by a timeline interactivity by the user [Rya06] – its narrative being slider or menu items, thus showing changes and reader-driven [SH10]. Nonlinear-based interactive comparing information. A high level of interactivity infographics provide the user with many ways to explore enables users to explore the infographics and to interact and query the visualization – including free exploration with data and information, e.g., by inputs, filtering or without predefined navigation paths. Navigation tools data retrieval (Figure 4). for nonlinear infographics include filter, input box, data We analyze only the degree of interactivity, but do query or brushing (various visual representations of not identify the ways of manipulation as in [SH10], like same data).

This type is a hybrid of the author-driven and reader-driven approach [SH10] that enables the author to communicate his message using a predefined path, but 56 Interactive Infographics in German Online Newspapers still allowing the user a certain amount of selection 3 Analysis of Utilization of Interactive ability. Navigation tools for linear-nonlinear infographics include interactive timelines, time Infographics in German-speaking Online controller, and integrated navigation menu. [Web13] Newspapers Interactive infographics have various occurrences and 2.3.3 Communicative Intent are used for multiple purposes. However, not all types Based on Nichani und Rajamanickam’s taxonomy of interactive infographics can be utilized in data-driven [NR03] we use the following categories to represent the journalism. In this section we analyze which interactive communicative intent oft interactive infographics: infographics are used in data-driven journalism in Germany, Austria and Switzerland to efficiently present • Narratives: Stories told from a distinct point of view complex data and their causal relationships.
