Visualizing RDF models

rapper -i turtle my.ttl -o dot > my.dot
dot -Tpdf my.dot > my.pdf
fdp -Tpdf my.dot > my.pdf
circo -Tpdf my.dot > my.pdf
twopi -Tpdf my.dot > my.pdf
sfdp -Tpdf my.dot > my.pdf

Do not forget to add the “rdf” prefix to the Turtle file

@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
