MDE in Support of Visualization Systems Design: a Multi-Staged Approach Tailored for Multiple Roles

Description

Visualization systems such as dashboards are commonly used to analyze data and support users in their decision making, in communities as different as medical care, transport and software engineering. The increasing amount of data produced and continuous development of new visualizations exacerbate the difficulty of designing such dashboards, while the visualization need is broaden to specialist and non-specialist final users. In this context, we offer a multiuser approach, based on Model Driven Engineering (MDE). The idea is for the designer to express the visualization need by characterization, according to a given taxonomy. We provide a Domain Specific Language (DSL) to design the system and a Software Product Line (SPL) to capture the technological variability of visualization widgets. We performed a user study, using a software project management use case, to validate if dashboard users and designers are able to use a taxonomy to express their visualization need.
