In June 2025, Sindre Breda developed a data-driven demonstration capability for the graphistry/pygraphistry repository by introducing the RedTeam50k dataset. He focused on data engineering and dataset management, aligning the new dataset with the data wrangling processes established in the UMAP-demo workflow. Using CSV as the primary data format, Sindre ensured the dataset supported realistic data flows for demonstrations and testing, particularly in Microsoft Kusto environments. This work enhanced the repository’s demo and testing infrastructure, streamlining onboarding for clients and internal teams. The project demonstrated a focused, well-scoped engineering effort, delivering a single, robust feature without addressing bug fixes.
