Managing dependencies between software services is a crucial task for any company operating cloud applications. Visualizations can help to understand and maintain these complex dependencies. In this paper, we present a force-directed service dependency visualization and filtering tool that has been developed and used within SAP. The tool's use cases include guiding service retirement as well as understanding service deployment landscapes and their relationship to the company's organizational structure. We report how we built and adapted the tool under strict time constraints to address the requirements of our users. We further share insights on how we enabled internal adoption. For us, starting with a minimal viable visualization and then quickly responding to user feedback was essential for convincing users of the tool's value. The final version of the tool enabled users to visually understand company-wide service consumption, supporting data-driven decision making.
