Researchers and practitioners increasingly recognize the relevance of the complex business environment in which companies develop, produce, and distribute their services and products, which we refer to as business ecosystems. In scientific research, the characteristics of business ecosystems, including the changing relations
between ecosystem entities, are often visualized. We conducted a systematic mapping study analyzing overall 136 papers to identify types of visualizations used in the business ecosystem context. We provide an overview of 17 visualization types and their frequency of application in scientific literature. In addition, we collected visualization tool requirements, which we enriched with our own experience visualizing business ecosystems with practitioners, leading to overall nine tool requirements.
