org-analyzer is a tool that extracts time tracking data from org files (time data recording with `org-clock-in', those lines that start with "CLOCK:"). It then creates an interactive visualization of that data — outside of Emacs(!). In order to run the visualizer / parser you need to have java installed. This Emacs package provides a simple way to start the visualizer via `org-analyzer-start' and feed it the default org files. See https://github.com/rksm/clj-org-analyzer for more information.
