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.

Pixie – A full-featured 2D graphics library for Nim
Reminds me of BGRABitmap from Lazarus/FreePascal.
https://github.com/bgrabitmap/bgracontrols
(BGRAControls contains the BGRABitmap components).
It's sad Lazarus/FreePascal doesn't get much play, because high quality libraries like this have existed for years for it and it seems to not get much traction.

Client-side scripting for in-browser graphics.
It appears that there's a port of Cairo to Go which also targets webassembly. https://github.com/tdewolff/canvas

Processing equivalent in GoLang
https://github.com/tdewolff/canvas/blob/master/examples/opengl/main.go can draw primitves but i think it would be a bit hard to do event based animation

tdewolff/canvas: vector graphics in Go (mayor update)
canvas has a focus on using state-of-the-art algorithms regarding numerical approximations, see https://github.com/tdewolff/canvas#articles for a list of publications used in this library
I see, you'd like to specify the exact output pixel size for the rasterizers? To be honest, the floats are being multiplied and rounded, so given a set of canvas dimensions in mm and a DPMM should be fine in your case. In any case, I've opened an issue to calculate the resulting DPMM automatically to get a certain pixel width and height: https://github.com/tdewolff/canvas/issues/78
Yes! See https://github.com/tdewolff/canvas/tree/master/examples/gonum-plot for an example using gonum-plot. You should be able to plug-and-play to use the canvas library!
