Create graph from opening_hours

I am trying to create a graph over time (days of the week) showing when shops are open/closed within a certain area.

I've had a look at some of the existing parsing tools available but none seem to be able to convert the OSM opening_hours data into something that could be graphed. I'm not experienced in Python or any other programming language so I can't really code a script myself.

Are there any tools that I could use to help me? Or any tips that people may have?
