> SOLR-8925 is shaping up nicely. It would be great if Solr could support outputting graphs in GraphML. This will allow users to visualize their graphs in a number of graph visualization tools (NodeXL, Gephi, Tulip etc...). This ticket will create a new Graph handler which will take a Streaming Expression graph traversal and output GraphML. A new GraphMLResponseWriter will handle the GraphML formatting. In future releases we can consider supporting other graph formats.
