  Data visualisation assists domain experts in understanding their data and
helps them make critical decisions. Enhancing their cognitive insight
essentially relies on the capability of combining domain-specific semantic
information with concepts extracted out of the data and visualizing the
resulting networks. Data scientists have the challenge of providing tools able
to handle the overall network lifecycle. In this paper, we present how the
combination of two powerful technologies namely the REST architecture style and
JSON Schema/JSON Meta Schema enable data scientists to use a RESTful web
service that permits the construction of knowledge graphs, one of the preferred
representations of large and semantically rich networks.
