问题
I would like to show number of visitors on a site since beginning of the month, number of users on the current day and currently on site.
I have Google Analytics installed, I tried to solve this issue with Embed API by enabling Google Analytics API from developer console - but I requires user authorization, etc.
What would be the easiest way to show analytics on-site without user authentication and accepting access by Embeded API, etc. Application is written in Angular, so Javascript API is the one I look for.
Thank you for any suggestion.

Authorization has to happen in order to get the data you want. Either you can let visitors to your site authorize themselves, or you'll have to authorize server-side on their behalf.
Once authorized, you can do something similar to what the Third Party Visualization Embed API demo shows. It uses a custom ActiveUsers Embed API component and includes the source code to show how it works.
Whether you use the ActiveUsers component or not, the basic gist is that once the users is authenticated via the Embed API, you have access to the method gapi.client.analytics.data.realtime.get, which you can use to query this data.
Here's where that happens in the source code for the ActiveUsers component:

Authentication with the Analytics service is mandatory. But the OAuth 2.0 Service Accounts (for Server to Server Applications) can be used to automate it in many cases.
It's unclear to me (from a quick scan) if the Auth options of the Embeed API would work with the automated authentication scheme, you may want to go through the details.
You should be able to use the Analytics Core Reporting API and maybe the Analytics Real Time Reporting API (beta) which work with the automated authentication according to their guides (look for the Authorisation sections on the left frames of the respective guides).
Donno if this qualifies as easy, tho, YMMV :)
