I have been working on python3 tool that makes use of the the generated logs out of BRO, it uses plotly-library to make interactive plots and chart that would ease the process of analyzing the alerts.
it would be a pleasure if anyone is interested in further development of the code, or even suggest features to make the program more usable.
you can check the code on GitHub repositiory :
