Sparql Query Vizualization

question contest:

i’m currently working on a visualizer for SPARQL-queries. Yes, the focus lies on the visualization of the queries and not the results. It might be easy to visualize the results of a query, but how to visualize the query itself when you have more complicated features to consider like filters, group by’s etc..

This question is more about inspirations, because i would not have problems in implementing the visualization in Javascript, but rather struggle in ideas how to make them understandably visible.

Thanks for links, ideas, papers, etc..
