For example, give the SPARQL endpoint http://togostanza.org/sparql, the following query retrieves the NCBI classification for the tardigrade family Hypsibiidae:
By outputting the results as a list of parent-child pairs, it is straightforward to convert the output of this query into a form that D3 accepts, so we can get a tree like this:
The ability to quickly generate trees, charts, and maps from SPARQL queries makes things a lot easier. We can play around a little and explore things. The strength (and challenge) of SPARQL is that it is very open-ended, you can more or less develop queries to do anything. Being able to visualise the results will help guide that exploration.
