Spline Curve using JPG Image

[#1]

Hello!

I hope you are doing well. I am new to J software and I am attempting to do a spline curve. I do not have the raw data points but rather an image I have attached below. Is it possible to load this image in J and do a spline curve? I attempted to do a load 'image' but that did not seem to work. Any guidance and help is much appreciated. Thank you.
