There is already a vast amount of Linked Data on the web. What is missing is a convenient way of analyzing and visualizing the data that would benefit from the Linked Data principles. In our previous work we introduced the Linked Data Visualization Model (LDVM). It is a formal base that exploits the principles to ensure interoperability and compatibility of compliant components. In this paper we introduce a vocabulary for description of the components and an analytic and visualization pipeline composed of them. We demonstrate its viability on an example from the Czech Linked Open Data cloud.
