Custom real-time value viewer

Hi,
I’ve seen value viewer docs that allows providing custom html which is great, but I was wondering if there is a way to vizualize progress of a task, let’s say chart that updates as soon as next data batch arrives, or table that adds next row when there is new data? Currently I’m using console.log for that but it’s bit limiting.

Thanks!

@me1000 is there a way to clear output of running runkit? Tried console.clear() but it has no effect.
Thanks!
