Proper datasets

@Saurabh7
Currently, all toy datasets are either non-sense, or not informative. I suggest we re-place them with meaningful stuff.

Like a blob of two Gaussians for classification toy. And a real classification dataset, you can come up with something nice.
For regression, the sine wave is cool, what about a real dataset like CO2

@karlnapf Just found out, GMM toy data is already available in the dropdown for classification demo. Maybe we should make it the default one rather than checkboard...

@karlnapf This should be fixed?
