This model came from a real world need to analyze a list of requirements received as part of a Request for Proposal. These situations typically involve sifting through a long list of details to determine what is in there. The visualizations enabled us to determine if items were missing for roles, distribution of requirements by priorities, etc.
The Strippet browser custom visual provided a nice card interface for each requirement. The tree view control is used to create a proportional representation of the number of requirements in a given state.
