Now this animation is available for the 1000 sequences decomposed on my website.
Accessible from the 3Dgraph, 2Dgraph500terms and 2dgraphs pages ➡️ https://decompwlj.com
A little more work on axis sizing and controls.

tracing jit compiles a single linear path through our loop, even across calls. every exit and deviation of control flow is handled as a jump to a exit stub.
code quality could be improved. for example a pair of instructions lea xx(%rip), %rax; mov $1, (%rax) could be merged into single rip relative move. but the main overhead is the dance around initializing and destroying stack frames. most of the code is just this. actual loop while($i--) is compiled into a quite efficient binary. php was able to infer that the variable $i can be only integer and never touches its type. nice. but the rest is miserable.
(btw, php jit is the work of a single guy, which is more than impressive.)
