title: shape recognition with Javascript/HTML
body: <p>For a little project it would be nice if I have the possibility to make some shape recognition. It is a Webpage which shows a Visio Diagram. It shall be possible to click on one  of the shapes (only rectangles) and then additional Information shall be shown. To areas of a picture clickable is pretty easy in HTML. But unfortunately there are tons of several diagrams with tons of several shapes. The only method I know to make areas in a picture clickable is with fix pixels. Unfortunately the Visio diagrams change pretty often and so I would need to update the pixels often. Maybe you know any possibility with the known web-languages to recognize the shapes and set the areas in a dynamic way? </p>
  
  <p>So long,
  Stefan</p>
