+We start by converting from a `plotnine` plot to a `matplotlib` plot using the `draw()` function. We can also set the size of the plot (and resolution if you want using `fig.set_dpi(300)`). The `plt.gca()` extracts the axes from the existing `plotnine` plot.
 
 The `ax_text()` function from `highlight-text` adds text at the desired x- and y- coordinates, where the coordinates are based on the data range in the original plot. The `vsep` argument controls the line spacing, and `fontname` is used instead of `family`, but otherwise the arguments work similarly as in `plotnine`. We use the `ax_text()` function twice - once to add the coloured annotation, and once to add the caption. Finally, we show the plot.
