I tried to scrap the data available in behind the graph on webpage. I don't found storage data in source code(html page).

I tried to found data in html page but it not found. Then i tried to another way -goto inspect --> then Network --> click on XHR -->then reload page

Code:
from bs4 import BeautifulSoup 
import urllib.request
import _csv
import  pandas as pd
urlpage= 'https://display.bfmio.com/prebid_display'
...
