At Graphistry, we help investigate & correlate events, initially for security logs. E.g., Splunk & Sumo centralize data and expose grep + bar charts, then we add visual graph analytics that surfaces entities, events, & how they connect/correlate. "It started here, then went there, ..." . We currently do basic ML for clustering / dimensionality reduction, where the focus is on exposing many search hits more sanely. Also, some GPU goodness for 10-100X visual scale, and now we're working on investigation automation on top :)
