# A simple notebook This trivial notebook shows the possibilities for data analysis on RDF graphs, including the generation of charts using the [C3.js](http://www.c3.org) library. First we just demonstrate querying for triples.

rdf(S,P,O).

Below we show how the C3 renderer can be used to create a diagram on the distribution of triples in the RDF store.

findall(Graph-Count, limit(10, order_by([desc(Count)], rdf_statistics(triples_by_graph(Graph,Count)))), _Pairs), Chart = c3{data:_{columns:_Pairs, type:pie}}.
