2 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO We all agree Visualizing data, creating images out of data is the beeline in bringing statistical information to the users. But: There are many dangers and open questions lurking alongside this route.

9 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO Offering graphs:User-side interactivity User-created graphs are increasingly offered. Statistical Institutions use a large set of graphical information types. Bottlenecks in dissemination services, advanced technologies and demands from users push interactive graphs. There are several types of interactive graphs.

10 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO User-side interactivity 1. Populating graphs with data in an automated way. Interactivity is restricted to building a graph on the basis of predefined tables or online databases. The result: ad hoc graphs for a first analysis
11
11 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO User-side interactivity 2. Giving users the possibility of changing the appearance of graphs. Choosing bar or pie chart presentation, colours and size are part of this interactivity. A playground for adapting presentation aspects to user preferences.

12 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO User-side interactivity 3. Offer an interactive choice in information. In predefined graphs variables can be changed and new information elements displayed. http://www.bfs.admin.ch/bfs/portal/en/index/themen/03/04/blank/key/lohnstruktur/nach_branche.html

13 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO User-side interactivity All of these graphic types can also be dynamic. Users can decide to let variables or developments in time be presented in a film. Such films are attractive but usually difficult to follow..

14 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO User-side interactivity 4. A combination of interactivity, dynamics and explanation. It is interactivity conceived, controlled and presented with commentary to the users by intermediate persons. This television-like presentation leads to fascinating statistics courses for a wide public. Hans Rosling

15 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO Producer-side interactivity The number of graphics tools is quite large. How do we find the best and fastest way to produce?
16
16 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO Producer-side interactivity Automated production of graphs with software like Excel (or some Online-Databases) leads to “working graphs” but not necessarily to “publishing graphs”. High-quality graphs need authoring. But this becomes increasingly difficult. So we observe an increasingly important trend in making the publishing of high quality graphs and maps both cheaper and....faster. How to? Following this approach authors have to be provided with all the necessary interactive tools to publish graphs. A step further would be to use more advanced specific procedures so as to ensure (semi-)automatic production.
17
17 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO Template-driven graphics production Specialists can use semi-automatic tools to build templates for graphics and to introduce data via i.e. Excel files or xml/SDMX. This technique allows for the fast and easy updating of an application: it is kid's play to add an additional year to a graphic.

18 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO Template and graphics power to the authors Granting authors the direct publishing power in the field of visualizations is a further approach. Here, Web Content Management Systems (CMS) open new possibilities. Authors can edit texts and introduce data for graphs.

19 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO Template and graphics power to the authors Predefined CMS templates for author usage and the central activation service ensure quality before publishing. In a future step these graphs will be exported via xml to other publishing tools, opening in this way all sorts of cross media opportunities...

20 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO Automatically generated high-quality graphs The last step i.e. the automatic production of high quality graphs is not yet achieved in Statistics Switzerland. Through this process, quality controlled templates would be filled and updated with data via a direct database access. So graphs presented in a web page or pdf-reports could be produced and presented easily and rapidly. Projects aiming to achieve this and to combine graphic templates and databases are underway.

21 Interactive visualization from a user and producer perspective| UNECE May 2008 A. Grossenbacher Federal Department of Home Affairs FDHA Federal Statistical Office FSO We’re working on it An international discussion about generating high-quality visualizations of data is of fundamental interest for us all.
