API: Website CORS not allowed #2807
Description
Hi!
I just discovered your package, and I've noticed a bug on the website during the API example, with a "CORS failed" request being returned (https://nivo-api.herokuapp.com/nivo/charts/bar).
It seems this isn't the only graph affected.
Also, I found another small visual "bug": when the menu is open, the background tabs are no longer accessible.
Have a good day, team :)
