Google math graphing not working anymore ?

Hi !

As you probably know, it is possible to plot mathematical fonctions directly on Google Search’s website, just by typing the function you are after.

I have tested it earlier, but lately, it won’t work at all.
Still, my computer has WebGL compatibility, and i use Chrome/Firefox.

Have they removed it ?
Can someone test it for me ?

Just type something like:

in google search.
