Visualizing data is a widely used approach to derive value from data. Within the context of business ecosystems visualizations have proven to enable ecosystem stakeholder to take better-informed decisions. Thereby, the collection of relevant data is often referred to as a major challenge. In this paper, we present knowledge extracted from visualizations of an emerging mobility business ecosystem. Our research approach consists of the identification, assessment, and evaluation of open Internet data sources, followed by the extraction and visualization of this data. We identify groups of participating organizations, the main relation type between organizations, and the role of mobility information and mobility service provider as two new organization types within the mobility ecosystem.
