Flowing Fix: How do I get those data points off an image? [revisited]

A while back, we posted how to get data off an image by running digitizing software on your local system (see the link to the prior post below). However, if you have limited admin access to install/run the software (or don't want to install software), WebPlotDigitizer is a web-based tool that runs directly your web browser https://automeris.io/WebPlotDigitizer/ that allows you to extract data from plots, images, and maps

Flowing Fix: Mathpix Snipping Tool

There are times when you need to replicate an equation or block of text from a PDF file. If the PDF file was converted from a typed file, chances are that the text in the PDF can be selected. However, for equations (and if the PDF is image-based), you were out of luck, until now. Mathpix Snipping Tool is perfect for capturing a screenshot of the equation or text and automatically converts it to LaTeX. It is almost magical, capable of converting typed and handwritten information to LaTeX.
