Despite the wealth of information contained in the Web of linkeddata, the current limitations and entry barriers of the Semantic Web technologies hinder the users from taking advantage of these information resources. linkeddatavisualization can alleviate this problem. In this paper, we adopt a proper linkeddatavisualization model, design linkeddatavisualization algorithms, and develop a lightweight, easy-to-use prototype tool, LODViewer, using the platform independent Java Script language. LODViewer can visualize different sources of RDF data including SPARQL endpoints for linked Open data (LOD) sources, and display the data in different graphic illustrations. Our case studies have verified the effectiveness and realizability of the proposed method. The time complexity analysis and experimental test show that the run-time of the proposed algorithms approximately exhibits a linear growth rate as the visualized RDF triples size increases.
