Which of the options for a public service with the publication of data, in your opinion, is more optimal in this case?

Question

PHP

I have a certain "system" (a set of self-written scripts) that collects, processes and accumulates some data, gives various recommendations / data / statistics based on them, and generally builds tables and graphs.
I want to make a public service so that everyone can see this data, but I don’t want to do it as a website, because. I consider this a morally obsolete process, and again, the site will have to be twisted to be seen, in my opinion, the mobile application and the VK group are more optimal.
The data is stored in SQL and REDIS, and then the script builds various tables and graphs based on this data (final result). Of course, I see all this on my website (some kind of admin panel), but it is not for the public, but only for me personally.
There are 2 options:
1) create a VKontakte group so that the final data is published there, in the form of posts (automatically), for example, one VK post every 5 minutes. In this case, if these data are of interest to the public, the group is free to expand. There are 2 problems here: using a script to generate tables and graphs for VK posts, for this you need to reinvent the wheel :( For example, generate some pictures. Or something else. 2
) create an application for Google Play, and describe there the data received, for example, via the API from the script in the form of JSON, in which case you will have to draw graphs and tables already through tools for Android Studio, for example. The problem here is that I got acquainted with Java recently :)
What option would you recommend to me, maybe some of your own. In short, you need to publish some text and a table, at least, but also a graph is also desirable.

Answer 1

And why not just open your admin panel outside, finishing it as needed? This is obviously the least expensive way, and quite user-friendly.
And it would be very good to give out api so that you can receive data for independent analysis.
According to the options you suggested:
1)
a) There is a limit of 50 posts per day in communities
b) Without knowing what kind of data you have, it is difficult to judge the demand for them by the VK audience, but in any case it looks strange
2) The application does not promote itself (without financial investments). This can be a good thing in addition to the main channel.

Answer 2

Share the RESTful API with the swagger description.
And a small advertising program with graphs as an example.
