The recent explosion of freely available RDF datasets on the Web calls for new tools and techniques for semantic-enabled exploratory browsing. We present ENT, an HTML5-based tool that guides the user through the navigation of RDF graphs avoiding the visualization of information resulting irrelevant for the exploratory task. Thanks to a hypertree-based visualization of the data-space, the user has a clear picture both of his/her navigation path and of the information he/she may discover.
