web scraping an interactive map for cell dimensions

I have done a lot of research both on stackoverflow and other site trying to scrape data from an interactive map on this website http://ift.tt/2hieOHH all to no avail. I need the booth size for each booth(cells) on the map. The booth size appears when you point on any booth on the map. I have check the developer console to see if the data is loaded from a json file, but there was none. Instead the page source contains some js files which i think the data is loaded from it. Here is the js files from the page source: http://ift.tt/2h2VJxc

Please how do I scrape for the booth sizes using python.

Thank you in anticipation.

P.S: I'm new to stackoverflow and this is my first question.
