Mark-Jan Bludau Information Visualization

Mark-Jan Bludau is a research associate at the Urban Complexity Lab. His main field of interest lies in information visualizations in general and cultural collection interfaces.

He obtained a Bachelor’s degree in communication’s design at the FH Aachen as well as a Master’s degree in Interface Design at the FH Potsdam. During his bachelor’s degree, including a semester abroad at the University of Buenos Aires, he was mainly interested in the creation of static and animated displays of information and received an Information is Beautiful Award for his infographic-based bachelor’s thesis. In his master’s studies he focused on interactive data visualizations, concluding with his master’s thesis, an explorative art collection interface in collaboration with the Berlinische Galerie, where he experimented with perspective-dependent visualizations.

Scalable Exploration. Prototype Study For The Visualization Of An Author’s Library On The Example Of ‘Theodor Fontane’s Library’.

— In Book of Abstracts of the Digital Humanities conference (DH) 2019: Complexities. Utrecht (The Netherlands), 2019

This article presents a prototype for the explorable and scalable visualization of an author’s library and its reading traces. It aims to combine design-oriented approaches to the visualization of cultural collections with philological, archival and library research questions.

The visualization concept developed in the project places a special focus on continuous navigation within an author’s library that can be zoomed and filtered at several granularity levels and that allows the exploration of individual objects as well as their comparison. It focuses on the experience and comprehensibility of the collection as a whole and the reading and usage patterns reflected in it, as well as provides access to individual phenomena.


Relational Perspectives as Situated Visualizations of Art Collections

— In Book of Abstracts of the Digital Humanities conference (DH) 2019: Complexities. Utrecht, The Netherlands, 2019

With relational perspectives we explore the potential of a new type of approach for the exploration of cultural collections. Cultural collections can contain thousands of artifacts, of which each typically possesses a diverse set of properties constituting a unique relationship to the rest of the collection. Therefore, to create an appropriate representation of the complex data of each underlying artifact, oftentimes it is not only interesting to get an overview about the entire collection from one perspective, but to explore the particular context and relations of individual items. To investigate the potential of relational perspectives we selected an art collection as a particularly promising case study. By following a collaborative and iterative design process with an art museum, we developed a web interface that contrasts a collection overview with three perspective-dependent views to examine the viability of this approach and to expose the diversity of each artifact.


Skalierbare Exploration. Prototypenstudie zur Visualisierung einer Autorenbibliothek am Beispiel der ›Handbibliothek Theodor Fontanes‹

— in: Konferenzband zur DHd 2019 Frankfurt & Mainz - Digital Humanities: multimedial & multimodal, 2019

Der Beitrag stellt einen vom Theodor-Fontane-Archiv der Universität Potsdam in Kooperation mit der Fachhochschule Potsdam entwickelten Prototyp zur explorier- und skalierbaren Visualisierung einer Autor*innenbibliothek und der darin enthaltenen Lektürespuren vor. Ziel ist die Verbindung gestaltungsorientierter Ansätze zur Visualisierung kultureller Sammlungen mit philologisch-, archiv- und bibliothekswissenschaftlichen Forschungsfragen. Das im Projekt entwickelte Visualisierungskonzept legt einen besonderen Fokus auf die kontinuierliche, auf mehreren Granularitätsebenen zoom- und filterbare Navigation innerhalb einer Autorenbibliothek, die die Erkundung einzelner Objekte ebenso zulässt wie deren Vergleich. Die Erfahr- und Erfassbarkeit der Sammlung als Ganzes und der sich in ihr abbildenden Lektüre- und Benutzungsmuster stehen dabei ebenso im Zentrum wie Zugänge zu Einzelphänomenen.

Climate change severely affects Alpine regions. Adaptation to climate change is needed in order to deal with these impacts, but the implementation of national adaptation strategies is inhibited by multiple obstacles. Regional strategic frameworks are just emerging, adaptation is of little priority to local agendas and policy mainstreaming is limited on all administrative levels. This paper provides a better understanding of the governance of adaptation to climate change in Switzerland, an example of a federal system with a strong focus on subnational levels and multilevel governance. We conceptualize governance as a network of policies, measures, actors and knowledge, and visualize their interactions using D3.js, a data-driven JavaScript library. The findings illustrate the typical division of labour in federal multilevel governance systems. The national level provides a strategic framework and funding and conducts coordinating measures at subnational levels, especially the local-level implementation of concrete measures. Conducting comparable mappings for other countries would allow interesting comparisons and insights into common barriers and opportunities to adaptation to climate change.
