Thank you very much for sharing the "Rutas del Conflicto" project. This gives great inspirations for similiar projects. I am following Kivu Security Tracker for a while, a joint project of Human Rights Watch and The Congo Research Group at New York University. https://kivusecurity.org/
They are also using latest data on violence in Eastern Congo, include them in their data bases and provide long term visualization. It seems to be a great means to "connect the dots". Single fatalities, as tragic as they might be, don't provide much information beyond short headlines. Long term patterns and trends are much more relevent to identify bigger stories. In this case, the researchers reveal information on the strenghts and movements of the many local militias.
I guess this is a great example showing that data visualisation ist a powerful tool beyond journalism and very useful for academic, non-governmental and civil society organisations.
