title: Use of OCR to read node graphs
body: <p>I would like to code a program that will use a phones camera to read a node graph and then perform dijkstra's algorithm on it, displaying the shortest path.
  Could pytesseract or other OCR tools for python read node graphs (such as in the image. Real use would be on printed ones) and give me enough information to get node coordinates and what letters are next to them, as well as the positions of the edges/which nodes they connect and what numbers are next to them?
  Any help would be much appreciated.</p>
