Wishlist for sns.scatterplot

Open comment thread for functionality that would be good to have in a sns.scatterplot function. Some things that have been mentioned are:

• Scaling point size off a continuous variable that isn’t directly interpretable as a point size (cf. #310)
• Better default colors (although #293 would also fix this)
• A better interface for handling continuous point coloring in a FacetGrid context, this currently requires a bit of a hack as color is the fourth positional argument so you would need to pass in a dummy argument for size.
• Jittering x and y points (currently build into regplot)

What else?

In general, it’d be great to be able to change marker size/style depending on the data. E.g.

sns.scatterplot(data, x='PC1', y='PC2', hue='Disease', marker='Sex', size='SampleQuality')

It’s currently a drag to do this with sns.lmplot.

One thing I often wish for is the ability to specify a label for each point, that would be shown as text next to the point. This is very useful for scatterplots with a relatively small number of points which you want to identify individually (e.g., countries, company names, specific products), and it’s currently a pain with matplotlib because you can’t pass a vector of strings to a single text call. Ideally the point labels could then be turned on and off with a quick command.
