Great to see new tools in this space. So far we have been using WebPlotDigitizer, it has recently released new versions that stopped being open source but moved to be a paid software, requiring login, plastered with AI advertising terms.<p><a href="https:&#x2F;&#x2F;automeris.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;automeris.io&#x2F;</a>

Glad to see some work in this space. While I was doing my PhD all I had was <a href="https:&#x2F;&#x2F;datathief.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;datathief.org&#x2F;</a>, which usually did the job, but had some limitations and was Java-based. Definitely did some manual extraction from time to time.

looks great. Although in your example it seems like the y-axis is a bit off.<p>start: 0.05 vs 0.1<p>end: 0.65 vs 0.7<p>It&#x27;s a difficult example!
