Draw a plot of two variables with bivariate and univariate graphs.
绘制两个变量的双变量及单变量图。
This function provides a convenient interface to the [`JointGrid`](seaborn.JointGrid.html#seaborn.JointGrid"seaborn.JointGrid") class, with several canned plot kinds. This is intended to be a fairly lightweight wrapper; if you need more flexibility, you should use [`JointGrid`](seaborn.JointGrid.html#seaborn.JointGrid"seaborn.JointGrid") directly.
