Why we included this project
Charts published as static images often hide the numbers that made them. WebPlotDigitizer recovers those numbers by letting you load a plot, mark the axes, and let computer vision trace the series into raw coordinates. It pairs automatic detection with manual adjustments, so it copes with log-scale and polar plots that fully automated parsers tend to miss, not just straightforward line graphs. Because it runs in the browser, there is no install step, and the same measurement logic applies to ordinary image measurements. People mining figures for systematic reviews, preparing data for meta-analyses, or resurrecting values from old publications will find it a dependable tool that has been in use since 2010.
