This is a webapp for displaying X-Plane Desktop's usage analytics.
It uses the Dash (by Plotly) framework to produce interactive graphs.
See it live at dashboard.x-plane.com.
We deploy via Dokku (a self-hosted Heroku-like PaaS, which we run on Digital Ocean). You can Git push to ssh://dokku@dashboard.x-plane.com/dashboard and Dokku will handle the deploy for you:
$ git remote add dokku ssh://dokku@dashboard.x-plane.com/dashboard
$ git push dokku
