    I figured out a solution then found code out there to help get it done.

    Obviously, just lazy load the third-party script, in this case graph-comment's script.

    I did it with window.requestAnimationFrame and an isElementInViewport function, because that's how I run animations in the viewport.

    Then create a script element and inside of the check to see if script element exists, onload your third-party-scripts.

    Works 100% (okay, 99%)
