Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Step outside the Happy Path
Start by formalizing the architecture. You don’t need heavy enterprise methodologies like TOGAF; use formats that fit the team and product. Frameworks like arc42 are suitable for complex systems, while simpler projects may only need C4 diagrams supplemented with a few additional visualizations.

C4 Model - The Basics
Software Architecture is all about developing systems that scale and are maintainable. Clear visualizations will help teams to communicate the design effectively. The C4 model comes in handy for this task! But what is C4, and why should you care?

Turning the Crank: Design as a Mechanical Process
https://c4model.com/ is very useful for this. :-)
I've told it before, but when we were doing some clean sheet work a while ago I decided to use the C4 model and drew out the obligatory "Context" diagram with "user" "phone" "laptop" "app" sort of stuff... and then two hours later realized that because we had both an online and a semi-disconnected mobile app that could be offline, certain things -had- to use a queue and expect an arbitrary amount of time for a task to run, and it completely changed how we thought about the core of how we implemented something pretty important.
Sold. :-)

Vega – A declarative language for interactive visualization designs
What sort of maps are you wanting to build? https://c4model.com/ seems to be the more popular standard for this style at the moment. https://github.com/plantuml-stdlib/C4-PlantUML makes this somewhat easy to code out. (And I think most cloud providers have addons for it.)

Devs need system design tools, not diagramming tools
It sounded like it was working up to a C4 pitch but never got there. It bears a look exactly for this post's title.

Book: Just Enough Software Architecture
Simon Brown is another person who has done a far better job than me of "democratizing" software architecture for developers. His talks [1] and workshops on architecture are exceptionally effective and his C4 architecture modeling language [2] is getting real traction.
I have youtube videos too [3] but they aren't as effective.

Ask HN: Guidelines for making clear architecture diagrams
Second this.
Reference for anyone looking I to it: https://c4model.com/
There is also quite a lot of options for helping create these diagrams. I've found https://structurizr.com/ to be the best of what I've tried so far.
