Thank you for your response. I had experienced this as well. However after refreshing the page a couple of times the graphs broke down once again.
My specs are as following:
Browser: Google Chrome Version 50.0.2661.75 m (Google Chrome is up to date.)
OS: Microsoft Windows 10(.0.10586) Home 64bit NL.
GPU: AMD Radeon HD 6450 (Sapphire/PCPartner)
