Hi, I'm Gephi+Linkurious co-founder. I've found visualizing large graphs pretty useless beyond the "I see meatballs!" effect and my opinion, after a decade in the field, is that it's the wrong problem for data analytics.
Much more interesting information is discovered during the process of dynamically building a visualization that is focused on user questions. I see with Linkurious that investigators usually need to visualize less than 1000 edges of a 1M+ edges graph to get answers.
The ultimate answer is generally a small graph: Graphistry is a tool that helps you get there. Why that's hard is most Splunk, Spark, etc. queries will return a bunch of events, and each event has a bunch of metadata. A tool should help, not fall over.
I think you're referring to scenarios closer to why we created the visual playbook concept and our embedding APIs. Small visualizations are often a good starting point in investigative scenarios. Even better.. no visualization, just full automation. We find this thinking comes up when the investigative flow is more established and curated. With visual playbooks, teams can record & automate multistep flows, run them whenever an incident happens, take action, and share & document the results. If part of the incident involves a bunch of events, or the analysts wants to dig in, our stack won't fall over. Instead, it provides a full visual analytics session with multiple cross-linked data views.
And we're fans of Gephi. We GPU accelerated the core algorithm -- we may be coming from a different perspective and user base.
Our full investigation platform supports connectors like those, and to non-graph sources (Spark, APIs, ...). We found teams need more than just a graph db frontend, especially as we enable them to put in more data into a session than previous-gen technologies. Ex: we created visual playbooks for running repeat investigations and binding the result to an interactive visual analytics session.
We're actively piloting our investigation platform with interesting teams, so please reach out: info@gr...com.
I'm interested to see if anyone's offering a large-scale graph visualization that's not the "pulsating rainbow hairball".
