With the release of Solr 6 we’ve got the possibility of working with graphs when working with Solr (see more). Using the appropriate query we can retrieve documents representing a graph build out of our documents. The one missing piece was the visualization of the returned results. We thought we can fill that hole and we’ve developed a very simple tool to handle the visualization.

Let’s look at this new feature working both in old fashioned Solr master – slave as well as in SolrCloud.
