Hand-rolled, kettle-boiled, baked to perfection. Worth every minute at the bakery.
Summary
The article describes the development of a custom layout algorithm for visualizing control flow graphs in JavaScript and WebAssembly compilation, created as an alternative to existing tools like Graphviz and Mermaid. The author explains their dissatisfaction with existing visualization tools and details their process of building a specialized algorithm tailored to their specific needs for visualizing SpiderMonkey's Ion compiler optimization processes.

· 4 pulledWe recently overhauled our internal tools for visualizing the compilation of JavaScript and WebAssembly.
When SpiderMonkey's optimizing compiler, Ion, is active, we can now produce interactive graphs showing exactly how functions are processed and optimized.
I was not satisfied with the output of common tools like Graphviz or Mermaid, so I decided to create a layout algorithm specifically tailored to our needs.
The resulting algorithm is simp
