Whiteboard

Basic idea is to give data visualizers more freedom to create info graphics. At the same time be less restrictive on the data provider side and allow them to dump the data in a file instead of database. The data visualizers will then select the data files they're interested in, extract data and create an SVG out of it. The user can add any number of info graphics to welcome screen and swipe through those. If a data source/provider is missing, e.g. an app got uninstalled, all infographics depending on that data will be deactivated.
