Some time ago I remember seeing, perhaps in Twitter, a website in which you could upload say a jpeg of a plot and it has tools that allow you to recover the coordinates of points in that plot.

Does anyone know that website, or a similar tool?

In the past I had a good experience using engauge digitizer

This one seems very easy to use:

> Easy online tool for reading data from graphs, diagrams and plots (png, jpg, gif) and save data as CSV or JSON.
> Use manual or automatic estimation of the curve segments.
