What is Graphreader?
Graphreader is a perfect tool for getting numerical data from graphs and plots that are made up of images. People can use it to scan graphs, which gives researchers close copies of the original data to look at. Researchers, students, and workers who need to look at data from visual reports and publications will find this tool very helpful. Data privacy is respected, but users are told not to share private files because of the risks associated with cloud storage.
