amh, not get the CSV file thing,
if you have that data as a CSV file already the whole question makes no sense.
you not say how you get that data into what kind of array
you not link to your working/testing online project
the place of the function inside the sketch.js file does not matter
( as long it is not inside a other function…)
but the valid question is from where you call it?
as you not want any user interaction,
you must call it directly after the
without make your project available it is very difficult to help,
and i did write for you a set of functions regarding table already to give you a start…
now you just have to feed other data?
