An important thing I want to make you notice is that the graph describes something happened in the past, so you should use past tense. Another thing, there is no need to say the exact figure, just say for example "almost 193,000" instead of 192,971.
It is interesting to note that the country with the highest population in the world is also the
highest of rice production
. major producer of rice, with almost 193000 tons
Actually, from information provided by bar chart, China is the biggest of the amount rice producing in 1999 ,
reaching approximately 192.971 thousands of tons.
You already mentioned in the previous sentence, so i deleted this part, you can simply add the number at the end of the previous sentence (see above).
By contrast, the
rice producing of both nations America and Philippines respectively are considerably smaller.
amounts of rice produced by the USA and Philippines are considerably smaller
The former reaches mere 8.183 thousands of tons and the latt er only 10 millions of tons.
While the production of Japan is a little higher, at nearly 12 millions of tons.
Hope it helps
