I just wanted to add some additional info to the recent post on visualization that someone might find helpful. The post mentioned using Gephi and saving a SPARQL query to csv before loading into Gephi. There’s a Gephi plugin called Semantic Web Import plugin where you should be able to execute the sparql query right in Gephi. https://seinecle.github.io/gephi-tutorials/generated-html/semantic-web-importer-en.html
Sigma.js is always cool and it would be interesting to see what you could do with it and GraphQL. http://sigmajs.org/
RelFinder is an oldie’ but goodie’ although it’s showing it’s age with Flash but it would be interesting to see something like it with a more modern framework using Stardog Path queries. http://www.visualdataweb.org/relfinder.php
Vega. Visualization framework powered by D3. I’m actively looking into this but with the GraphQL queries this should be a quick win to put together some amazing visualizations. https://vega.github.io/vega/
yWorks does some good stuff although there’s no specific semantic web support but I’m sure a little work could put something nice together if you don’t mind paying for it. https://www.yworks.com/products/yed
Cytoscape. This always used to be a little clunky but I think it’s been updated recently and is looking shiny and new. http://www.cytoscape.org/
Maps. Too many options to mention but I’m sure there are some very cool things that can be done here.
