A method, a system and a computer program product for visually navigating contextual semantic data in a graphical overlay. The method includes overlaying a first lens, corresponding to a first domain and oriented in a first position, on the graphical overlay. A set of semantic data is displayed within the first lens. Rotation of the first lens to a second position reconfigures the semantic data such that a modified set of semantic data is displayed within the first lens. The modified semantic data and a ghosted image of the set of semantic data may be simultaneously displayed. A rotational position of the first lens is associated with various context aspects. A second lens, corresponding to a second domain, fully overlaps the first lens. Responsive to separating the first and second lenses, a circumscribed region is preserved within each of the first and second lenses while concealing a non-circumscribed region.
