Dataspace: exploration and analysis of high-dimensional data

Dataspace (dspace) is a data-science platform for scientists. Dspace is based on the assumption that a substantial part of data tasks can be broken down to a few primitives. These primitives are made available to combine in a lego like setting within a GUI. All actions performed are automatically logged and expressed as programming code. Code based work flows and GUI based work flows can merge seamlessly, enabling analyses without coding. At the same time you can easily use dspace with your existing code only when and where needed. dspace can be easily controlled through code and expanded by adding new actions. Data and expansions of dspace can be easily shared.
