I am a Tableau 10.5 desktop user working on a visualization to illustrate a matrix based on core values/mission/strategies. My data does not have measures and I need labels. Sunburst was not a good choice because labels would not fit. Sandkey might be an option, but I'm afraid it would be too complex for my users to understand (plus the labels issue). Anything I've tried ends up looking like "spaghetti" due to the many:many relationships.
Does anyone have any ideas on a format I might try? I am enclosing some screen shots and copy of the data.
I think a Sankey diagram would be ideal viz in your case. It is easy to visualize the flow, although at first look it might seem "what?" but I think it is very powerful in telling the story you're trying to tell.
