A focus + context compact scalable Gantt chart with drag-and-drop capabilities

Interactive Gantt charts are a well known technique to represent and edit interval and point events. Providing scalability to these editable charts in the presence of a large amount of events is a challenging problem that is underexplored. We propose a scalable and compact variation of editable Gantt charts based on focus+context, animation, and clustering. Drag-and-drop functionalities are available for relocating events in time. In this paper we discuss our design decisions when elaborating this interactive graphics, and how they may be applied to analyze sizeable sets of projects from a real company in the power generation sector.
