Automating Keynote - update Chart data

[omarko]

I have a Keynote file that has multiple Charts on multiple slides. I'm seeking a way to update the Chart data in an automated way (AppleScript perhaps)? I found some AppleScript examples online, but they don't seem to work in the current version of AppleScript. Is anyone aware of a method for accomplishing this today?
Here's an example:

tell application "Keynote"​

set theCSVFile to choose file with prompt "Select the CSV file containing the chart data:"​

set theChartData to paragraphs of (read theCSVFile)​

​

-- get the chart on the second slide​

set theSecondSlide to slide 2 of front document​

set theChart to chart 1 of theSecondSlide​

​

-- update the chart data​

set the data of theChart to theChartData​

end tell​
