Html+chart, how to make this work

my chart works if I don’t call a file “exchange.js”, but that would mean I need to add all the counter manually.

include is my work - Html-chart | Bubble Editor

I uploaded file to try in second pic , and called it via input. Should it be called in another way?

Pic 1, the spinner does not stop, keeps loading

Pic 2, this way I don’t get anything

Please help
