A key research issue for the commercial application of automatic presentation is the user
experience, which must support the flow of visual analysis. User experience has not been the focus of previous research on
automatic presentation. The Show Me user experience includes the automatic selection of mark types, a command to add a
single field to a view, and a pair of commands to build views for multiple fields. Although the use of these defaults and commands
is optional, user interface logs indicate that Show Me is used by commercial users.
