Opensource computer vision assisted software to help extract numerical data from images of plots, maps and much more.


A large quantity of useful data is hidden behind data visualizations that are only shared as images. WebPlotDigitizer makes it easy to extract this information using a mix of computer vision algorithms and manual tools.

WebPlotDigitizer has been cited in thousands of publications (and even XKCD). To cite in your own work, you can use the following information:

        url = {https://automeris.io/WebPlotDigitizer.html},
        author = {Rohatgi,  Ankit},
        title = {WebPlotDigitizer},
        version = {4.7},
        year = {2024}
