Scripts to generate network usage.
node index.js {active-timespans|active-weekly|lifespans}
active-timespans: number of active users, for a set of past time intervals
active-weekly: number of active users, per week
lifespans: how long users are staying active (retention)
The helper script, dump.sh, will run each script and write to a .json.
You can then host the folder and open index.html to see a visualization of the data.
