  Visualization tools usually leverage a single interaction paradigm (e.g.,
manual view specification, visualization by demonstration, etc.), which fosters
the process of visualization construction. A large body of work has
investigated the effectiveness of individual interaction paradigms, building an
understanding of advantages and disadvantages of each in isolation. However,
how can we leverage the benefits of multiple interaction paradigms by combining
them into a single tool? We currently lack a holistic view of how interaction
paradigms that use the same input modality (e.g., mouse) can be combined into a
single tool and how people use such tools. To investigate opportunities and
challenges in combining paradigms, we first created a multi-paradigm prototype
(Liger) that combines two mouse-based interaction paradigms (manual view
specification and visualization by demonstration) in a unified tool. We then
conducted an exploratory study with Liger, providing initial evidence that
people 1) use both paradigms interchangeably, 2) seamlessly switch between
paradigms based on the operation at hand, and 3) choose to successfully
complete a single operation using a combination of both paradigms.
