3D Path with a circular end

I'm trying to smoothen out the logo flow in around 0:06, but I'm terrible at making such 3D path using keyframes. (Don't mind everything else. I'll correct those minor bugs later) Only thing I'm struggling with is the logo fly in. And after a few Google searches without luck, I'm not sure what to do to make it look more natural/smooth. Any ideas?

This is how I've tried to put out the keyframes. I believe it would be better if those keyframes shown on the graph editor were curvy, but I'm not so sure if that's possible.

Any basic animation tutorial will tell you how to easy ease your keyframes.  Any basic graph editor tutorial will tell you how to convert your keyframes from linear to bezier or apply ease.

It's so basic I am reluctant to tell you because you apparently not even taken the time to follow an introductory animation tutorial.

Select your keyframes and hit F9.   If that doesn't look good enough then go here Get to know the basics of animation | 

You could also look through the "Window" menu and see if there's any word in there that looks like it night be useful.

When all is said done look for & study tutorials about using the graph editor or basic animation.

I'm not looking to ease the speed of the logo. I know the basics and I very well know how the easing works. But that's not what I'm trying to do in this case.

I want the path to be more fluent and not as pointy in it's directions. I could create a null layer and rotate that around the axis, but how would I then get the logo to fly in if it's linked to the null layer.

I don't have any experience with moving an object around in 3D space. And definitely not to make it look smooth.

There's the smoother tool in the windows menu.

There's the auto bezier button in the graph editor.

There's the drift across time function in the keyframe assistant.

There's other ways too.
