Integration with React application

I’m looking to transition our homemade time-series analysis plotting tools to Grafana. Does anyone know if:

  1. The Grafana UI can easily integrate into an existing React dashboard?
  2. How much effort is it to use Grafana with bootstrap (I thinking of using the Admin LTE 3 theme, which is based on Bootstrap 4)
  3. Is it trivial to add Grafana to an existing Dockerfile?
