Years ago, I used a tool called Ontopia to visualize the contents of a topic map file. I was able to build up a list of statement triples, load it into a server, and then navigate through the graph of relationships. Today, I have a similar need to model a graph of related items (people, places, events). My hope is that I could use RDF or JSON-LD to capture these relationships and to allow new types of relationships to be added to the graph. I have been exploring the visualization that is created in the JSON-LD Playground: https://json-ld.org/playground/ and this has some features that are useful. This tool creates a useful diagram if I keep the number of entities in my diagram fairly small (under 25). I have encountered 2 challenges - The visualization becomes unusable after about 50 entities have been added. - If I reference an entity defined elsewhere in the graph, that reference does not link to the definition of the entity. I have a couple questions - Is there a more robust tool for visualizing relationships found in JSON-LD (or RDF)? - Are you aware of a good tool for validating a JSON-LD (or RDF) file? - Would you have any other suggestions?
