Screenshot of the JHelioviewer application. The left part of the application window hosts expandable sections to manage and display time-dependent image layers, timelines, and event data. The main panel displays image data in a 3D scene that the user can interact with. The timeline panel in the bottom right displays 1D and 2D plots of time series, e.g. disk-integrated X-ray fluxes. Markers for solar events can be overlayed on both panels.
