Issue:
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?

 v0.9.0 (Unreleased)
 -------------------
 
-- Added the :func:`lineplot` function for representing relationships between numeric ``x`` and ``y`` variables with lines, potentially after conditioning on up to three other variables and semantically mapping those conditions with the color, size, or style of the lines. This function replaces :func:`tsplot`, but with an API that is more consistent with other modern seaborn functions and has both more flexibility (more dimensions of semantic mapping, better handling of dates) and less flexibility (fewer options for visual representing uncertainty). There is considerable new API documentation and there should also be a new tutorial.

 - Final removal of the previously-deprecated ``coefplot`` and ``interactplot`` functions.

+    Examples
+    --------
+
+    Draw a simple scatter plot between two variables:
+
+    .. plot::
+        :context: close-figs
+
+        >>> import seaborn as sns; sns.set()
+        >>> import matplotlib.pyplot as plt
+        >>> tips = sns.load_dataset("tips")
+        >>> ax = sns.scatterplot(x="total_bill", y="tip", data=tips)
+
+    Group by another variable and show the groups with different colors:
+
+    .. plot::
+        :context: close-figs
+
+        >>> ax = sns.scatterplot(x="total_bill", y="tip", hue="time",
+        ...                      data=tips)
+
+    Show the grouping variable by varying both color and marker:
+
+    .. plot::
+        :context: close-figs
+
+        >>> ax = sns.scatterplot(x="total_bill", y="tip",
+        ...                      hue="time", style="time", data=tips)
+
+    Vary colors and markers to show two different grouping variables:
+
+    .. plot::
+        :context: close-figs
+
+        >>> ax = sns.scatterplot(x="total_bill", y="tip",
+        ...                      hue="day", style="time", data=tips)
+
+    Show a quantitative variable by varying the size of the points:
+
+    .. plot::
+        :context: close-figs
+
+        >>> ax = sns.scatterplot(x="total_bill", y="tip", size="size",
+        ...                      data=tips)
+
+    Also show the quantitative variable by also using continuous colors:
+
+    .. plot::
+        :context: close-figs
+
+        >>> ax = sns.scatterplot(x="total_bill", y="tip",
+        ...                      hue="size", size="size",
+        ...                      data=tips)
+
+    Use a different continuous color map:
+
+    .. plot::
+        :context: close-figs
+
+        >>> cmap = sns.cubehelix_palette(dark=.3, light=.8, as_cmap=True)
+        >>> ax = sns.scatterplot(x="total_bill", y="tip",
+        ...                      hue="size", size="size",
+        ...                      palette=cmap,
+        ...                      data=tips)
+
+    Change the minimum and maximum point size and show all sizes in legend:
+
+    .. plot::
+        :context: close-figs
+
+        >>> cmap = sns.cubehelix_palette(dark=.3, light=.8, as_cmap=True)

+        ...                      legend="full", data=tips)
+
+    Use a narrower range of color map intensities:
+
+    .. plot::
+        :context: close-figs
+
