The bar chart shows how many product was outputted from different continents, including Asia, Europe and other countries. It gives information for couple of decades starting from 1840.
Overall, all of them were fluctuating slightly while the numbers for the rest of the world is tend to increase in most years, unlike in Asia and Europe.
Asia started at 50 in the beginning of a period. As time passes, the amount of production output declined and reached its lowest point at 20 in 19220. After it, they expanded the output and hit a point at 45 in the final year, trying to equalize with the beginning.
However, European states started with 10 units gap with Asian ones at 40. They rose until 50 in the middle of the period and slightly started to reduce to 28 at the end of the period. The number of units of them became equal with other countries in 1960 with around 37 that would be a peak point for the latter one. When it comes to the states in other continents, even though they began the period with only 10, there were upward trends until 1960, before a decline occurred at 32, in 2000.
