amp-graphics something desirable

### Description

https://developers.google.com/chart/interactive/docs/quick_start?hl=es

amp-graphics

What I need?
1 - Provide graphics using html5 code and attributes.

2 - Purpose of achieving this functionality

If this graphics api could be implemented in amp, the admin amp part could grow a lot since it would make things much easier in the administration part.
You have already achieved 80% with amp-form!

3 - Take amp further than the limits for which it was intended.
- Amp started with accelerated mobile pages
- Now try to become a html framework
- I see the ability to get amp in backend, amp in frontend and also implement it in a pwa.

4 - Here goes amp graphics

Maybe amp backend is not a thought that you have in mind but I have made the backend a reality and it is really fast as well as responsive and manageable with the mobile.
If I had graphics I could complete that administration because I also hope that all the amp pages of the administration are amp-valid.

### Alternatives Considered

5 - Alternative
Even without this functionality I will use amp-iframe until this functionality may be effective in the future.

### Additional Context

6 - Administration from the google cdn, the only way I can think of would be that with amp-access the cdn will send me a secret application code that I provide.
1 - Validate application.
2 - Validate user.
3 - reply with data that is private.

Is amp backend the future?

The issue names no source file, test, or concrete API; start by reviewing the linked Google Charts quick-start documentation and the existing amp-form and amp-iframe components. Work is not ready to start until the supported graphics API, required HTML attributes, and validation behavior are defined; done would require an agreed design and corresponding implementation and tests.
