Question was answered on SO

I didn't get you ?

Can you also please look into -

Error - Cannot read property 'constructor' of null while using Neovis.js

I'm not certain, but it looks like neovis.js may not be properly handling nulls returned in the Cypher query as a result of using OPTIONAL MATCH. Could you please create a Github issue here and we will investigate further and fix: https://github.com/neo4j-contrib/neovis.js/issues

and

The graph display on using Neovis.js can be more presentable

Default styling is pulled in from here: https://github.com/neo4j-contrib/neovis.js/blob/master/src/defaults.js You should be able to update styling in that visjs object to overwrite the defaults used by neovis.js.

Thank you for your consideration
