vizTreed3

A small python script to visualize easily instances in RDF datasets using treemap in d3.

We suppose you copy the content to this location {HOME_INSTALL}.

{HOME_PYTHON27} is your home install of python2.7.

To be sure, open a terminal an type python --version.

Dependencies:

python 2.7
SPARQLWrapper
JSON 

How it works

c:\python27> python makeJSONd3.py [-f] [-e] endpointURI 
copy/Y (mv) classesd3.json {HOME_INSTALL}
cd {HOME_INSTALL}
python -m SimpleHTTPServer or python -m http.server  (3x)   
open your browser at localhost:8000 or 127.0.0.0:8000

Visualization based on d3 Treemap

"Right view" shows the top first classes with a large number of instances

"Left view" shows the classes with fewer instances.

What can vizTreed3 con do for you?

Instant treemap-like view of an endpoint Filter by language tag "en", "fr" (-e, -f) Example: dbpedia fr instances at a glance

Why might you need viz-tree-d3 ?

• Check you converted all your raw/legacy dataset
• Quick view of instances in a given endpoint for further analysis
• screen scraping of RDF datasets for instance matching
• Dataset instance monitoring and quality checking
