Topography of Violence Visualizing antisemitic violence in Germany 1930–1938

How can acts of violence be visualized in an appropriate manner? Jews, Jewish institutions, and Jewish-owned firms and stores in the German Reich were subjected to increasing violence long before 9 November 1938. In cooperation with the Jewish Museum in Berlin, the project developed visualizations that present information about the dates and locations of many different acts of violence that took place between 1930 and 1938.

The project forms part of ongoing historical research that examines allegedly spontaneous manifestations of growing antisemitism before the Holocaust. From 1930 onward, and especially in the period from 1933 to 1938, the Nazis used racist slurs, antisemitic legislation, and violent assaults to threaten Jews on a local level and to exclude them from social, economic, and cultural life. As a result of this violence, which occurred in several waves, many of Germany’s two thousand Jewish communities ceased to exist by 1938.

The data set used for the project draws from contemporary sources and from extensive local, regional, and national studies carried out over the past seventy years. The research project subsequently focused on the question of how insightful, deliberate and ethical visualization forms can be found along interactive modes, enabling an animated overview and interactive exploration as well as the participatory enrichment of the data set. The results are an animated wall map and media station, which are integrated into the new permanent exhibition of the Jewish Museum Berlin, as well as a web-based visualization.

The visualization gives an overview of the acts of violence with their dates, locations, and perpetrators. The targets of violence are divided into three categories: individuals, Jewish institutions (synagogues, cemeteries, community institutions, private associations), and businesses (firms and stores). While the visualization does not provide a finalized or exhaustive survey of cases, visitors can search for particular places, years, or perpetrator groups. They are also invited to expand and enrich the data set by contributing their own knowledge of local incidents of violence.

Topography of Violence was a research collaboration between the Jewish Museum Berlin Foundation and the UCLAB, with the assistance of the House of the Wannsee Conference memorial and educational site. The data presented in the visualization are based on research by the Jewish Museum Berlin and by Marc Grellert of the Digital Design Unit, Technical University of Darmstadt.

Topography of Violence: Considerations for Ethical and Collaborative Visualization Design

— Computer Graphics Forum (Proc. EuroVis). 40(3), 2021
Based on a collaborative visualization design process involving sensitive historical data and historiographical expertise, we investigate the relevance of ethical principles in visualization design. While fundamental ethical norms like truthfulness and accuracy are already well-described and common goals in visualization design, datasets that are accompanied by specific ethical concerns need to be processed and visualized with an additional level of carefulness and thought. There has been little research on adequate visualization design incorporating such considerations. To address this gap we present insights from Topography of Violence, a visualization project with the Jewish Museum Berlin that focuses on a dataset of more than 4,500 acts of violence against Jews in Germany between 1930 and 1938. Drawing from the joint project, we develop an approach to the visualization of sensitive data, which features both conceptual and procedural considerations for visualization design. Our findings provide value for both visualization researchers and practitioners by highlighting challenges and opportunities for ethical data visualization.
