More and more data are being published in the form of machine readable RDF graphs over Linked Open Data (LOD) Cloud accessible through SPARQL queries. This study provides interactive navigation of RDF graphs obtained by SPARQL queries using Formal Concept Analysis. With the help of this {\tt View By} clause a concept lattice is created as an answer to the SPARQL query which can then be visualized and navigated using RV-Xplorer (Rdf View eXplorer). Accordingly, this paper discusses the support provided to the expert for answering certain questions through the navigation strategies provided by RV-Xplorer. Moreover, the paper also provides a comparison existing state of the art approaches.
