Add documentation section on high performance charting

[etimberg]

There are some techniques that can be used when charting a lot of points. We should add a documentation section on this topic.

Tips include

• Disabling bezier curve drawing
• Disabling lines or points
• Disabling line fill
• Turning off all animations

Is setting animation duration to 0 in the defaults the proper way to turn of all animations?

I was looking through this yesterday. I found at least 3 different animation settings 😦
animation.duration
responsiveAnimationDuration
hover.animationDuration
