        Assuming that we are interested in \emph{toxicological endpoints} we execute the template SPARQL query to receive results either as a static \emph{Dendogram} graph \emph{(Figure 1)} or as an interactive \emph{Sunburst} graph \emph{(Figure 2)}. To get all information about a subject we can use the SPARQL interface \emph{(Figure 4)} and write another query. We are always able to refine our query or investigate directly any kind of URIs from the result \emph{(Figure 5)}.

      \begin{block}{Use case 2: Investigate eNanoMapper data}
        Assuming that we want to investigate eNanoMapper nano material data we can simply choose one of the given SPARQL examples \emph{(Figure 6)} as a starting point. In this case we are interested in \emph{surface charge} and search for the zeta potential and its values. We receive a table with values and resource identifiers which point us directly to the resource page of the eNanoMapper database service \emph{(Figure 7)}.
