Lets-Plot: notes for pyramid

[ASmirnov-HORIS]

In section Common Plots / Pyramid there is a few issues with the plot:

• Clipped labels: unfortunately, the 20 character limit is hardcoded, so y labels are cut off. But the full text can be seen in the axial tooltip.

• Weird-looking tooltips on top of the pyramid: to improve tooltips displaying I suggest not to use identity statistic; you can calculate and add weight for users as shown below:

  g = (
    ggplot(df, aes(x="Stage", y="Users", fill="Gender", weight='Users'))
    + geom_bar(width=0.8)  # baseplot
    + coord_flip()  # flip coordinates
    + theme_minimal()
    + ylab("Users (millions)")
  )
  g

  It's already been replaced in PR #43, if you prefer that way of updating code.
