Hello!

Is there a way to format the data labels in An Advanced Example 
<https://google-developers.appspot.com/chart/interactive/docs/gallery/timeline#an-advanced-example>
 to 
make:

   - *President names to be centered*. I tried with annotation and 
   annotationText with no luck.
   - *Increase the font of all texts and bar size*. fontSize and 
   timeline.barLabelStyle didn't work for me.

Thanks
