-1. `bbc_style()`: has no arguments and is added to the ggplot chain after you have created a plot.

+1. `bbc_style()`: has two arguments and is added to the ggplot chain after you have created a plot. What it does is generally makes text size, font and colour, axis lines, axis text and many other standard chart components into BBC style, which has been formulated together with the Visual Journalism design team. The arguments allow to adjust the the font and the size of it.
 
 The function is pretty basic and does not change or adapt based on the type of chart you are making, so in some cases you will need to make additional `theme` arguments in your ggplot chain if you want to make any additions or changes to the style, for example to add or remove gridlines etc. Also note that colours for lines in the case of a line chart or bars for a bar chart, do not come out of the box from the `bbc_style` function, but need to be explicitly set in your other standard `ggplot` chart functions.
