Optimizing at the CPU instruction level in the browser w. Rust and WebAssembly

I don't think there's a way to change this math to work without taking the square root to get `distance`. It's possible that there is a way to change that to work with the squared forms, but I don't grasp the actual math going on well enough to determine that unfortunately.

Looking at the perf metrics for the full function's disassembly[2], square root-related instructions only account for a tiny amount of the program's runtime anyway.

That all being said, thank you so much for taking the time to read the post closely enough to come up with this idea!

super cool!

i've done my share of optimizations and benchmarking charting libs [1] but this goes deeper still.

SVG is not a good choice for large raw datasets when you need performance.
