A graphical browser for RDF objects. It takes a URI to some Notation-3 or XML RDF data and displays them as a graph using arbor.js. It's very minimal, very simple, and written in Flask.
To run it locally, execute:
python browser.py
Then, point your browser to the URI on which it says it started serving (usually http://127.0.0.1:5000) and browse some RDF data.
Some sample RDF data can be found here and here. An interesting example file to look at is http://www.w3.org/2000/10/swap/test/meet/white.n3.
