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.

Documentation as Code for Cloud Using PlantUML
My cross-platform desktop text editor, KeenWrite, allows users to define variables in an external YAML file. The editor calls out to Kroki[1] to convert text-based diagrams to SVG. The diagrams can reference variables and are rendered using EchoSVG[2].
KeenWrite[3] can produce PDF documentation from Markdown documents that has PlantUML diagrams with elements stored in an external, machine-readable file. Here are screenshots showing variables on the left, diagram text in the middle, and a real-time render on the right:

KeenWrite supports all diagrams offered by Kroki, which includes "diagram-plantuml".

EchoSVG: Pure Java SVG renderer with level 4 CSS selectors
EchoSVG is a library for handling Scalable Vector Graphics (SVG) images for various purposes, such as viewing, generation, or manipulation. By leveraging CSS4J, the library supports level 4 CSS selectors and RGBA color values (colors with alpha channel). To my knowledge, there are no other cross-platform, FOSS libraries that can correctly render MermaidJS diagrams outside of a web browser. I've tried Apache Batik, svgSalamander, resvg, rsvg-convert, svglib, CairoSVG, ConTeXt, and QtSVG.

Options for SVG / Text rendering on 2D pixel buffer
I've seen resvg as a potential pick, but it feels huge and seems to be importing skia, which itself is a whole rendering engine. Furthermore, I have no idea if I can pass my own 2D buffer to resvg and let it draw to it.

png crate gets an ultrafast compression mode, up to 4x faster decompression
For example, when converting vector SVG images to raster PNG images with resvg, most of the time is spent compressing the PNG image. This is a lot of wasted work if we just want to read the image instead of transferring it over the network! The fast compression mode eliminates all this wasted work, resulting in huge performance and efficiency gains.

Is coding in Rust as bad as in C++? A practical comparison
Just as a point of reference, I have a ~75KLOC project (includes dependencies) called resvg which takes just 4s in the debug mode and 8s in the release mode to build on M1 Pro.

Good example of high performance Rust project without unsafe code?
resvg is very fast, although the performance depends on the exact SVG you feed it - sometimes faster than librsvg, sometimes slower (although librsvg is also written in Rust now, it does use unsafe while resvg doesn't)

How to run this Rust project?
So I am absolutely clueless about Rust and just installed it an hour ago to use this tool called "usvg" https://github.com/RazrFalcon/resvg/tree/master/usvg

I think more Rust devs should focus more on rewriting software that is prone to exploitation
So, all you gotta do is rewrite the parsers. Funny you mention librsvg because there is a library called resvg that has a thumbnailer implementation for Windows Explorer. https://github.com/RazrFalcon/resvg
