Hi there @adepani,
did you find a way to split your data properly? Anyways Cell Splitter with comma as delimiter can help to split each player into separate column if that is what you are looking for.
Regarding your desired visualization. On first I thought Parallel Coordinates Plot node could be used but seems it doesn’t have option to stack lines so they are overlapped. Maybe Sunburst Chart can give you similar insight although in a different way.
Br,
