Cannot visualise graph

[sriniraghu16]

When I try to visualise the knowledge graph, I get the graph-data.js but the graph-index.js remains empty and html files are not generated.

================================
[Datasource] Processing : { name: 'vor',
mapper: [Function: circularGraphMapper],
output: 'graph-data.js' }

[Connected] to OrientDB [vor].

Can anyone help me regarding this ?

Based on your output, the word space data graph-data.js should be written with 118 nodes and 100 links. Can you try opening html/graph-universe.html?

The second part of your output suggests that you don't have an index data generated beforehand. This can be done with build_index.py.

I tried opening "html/graph-universe.html" but could find it empty !! Also the "build_index.py" too seems to be empty. what can be done to overcome this?

build_index.py will generate the index data onto your OrientDB. The output database will be created as vorindex. Can you check if it exists and whether it has some nodes/edges inside?
