What is bar chart?
- A bar chart or bar graph is a chart or graph that presents grouped data with rectangular bars with lengths proportional to the values that they represent.
- The bars can be plotted vertically or horizontally.

['Year', 'Asia', { role: 'annotation'} ,'Europe', { role: 'annotation'}],
['2012', 900,'900', 390, '390']
