: For a manual, code-based approach, you can use the built-in ginput function. A common workflow involves loading an image with imread , displaying it with imshow , and then using ginput to capture pixel coordinates and transform them into graph coordinates using a calibration algorithm .

: Specifically designed to digitize X-Y scatter plots from pictures. It is frequently updated and used for basic 2D data extraction.

: This tool uses an automated algorithm that can trace a graph from an initial point, picking the nearest point to the previously digitized one to speed up the process. Key Tutorials and Blog Resources
