Why do the samples contain 'Math.random()'?

Just saw this pop up in sonarcloud for me, and was wondering what the reasoning was for random key/ids to be added in the samples

Is this to force re-rendering? Does it break without random keys?

From the docs https://airbnb.io/visx/docs/threshold#Threshold_id

id for this threshold. If not set, multiple Threshold's on a page may conflict and interfere with each other.

thresholds use clip-paths which require ids. in examples, it doesn't matter if this is random. in your application you could consider using a unique id that is stable across renders. a simple solution (that would arguably demonstrate better react practices) would be to memoize this value with useMemo/useRef.

or useId() perhaps
