Recommendation centre: inspecting and controlling recommendations with radial layouts
, 2016 In this paper we propose to use radial layouts for representing the matching between the user’s interest and particular objects and/or categories. The technique supports the visualization of different data: we discuss here the relationships on social networks, the related videos on YouTube and topics in Wikipedia.
