Is this figure in US dollars? In 2005 US$, or 2007 US$? -- Mikeblas 19:21, 25 June 2007 (UTC)
 * It is in current market prices of the year in question.Anwar 08:55, 11 July 2007 (UTC)

I don't think this is a sensible representation of 'agricultural productiviy'. Japan producing 3 times as much as Russia, Canada or France - on what soil? They don't have any space. In order to be of any value, this map should reflect the true amount of crops, without the obviously considerable distortion resulting from local price differences.

Circles position
What's the criteria to position the circles inside the countries?--ClaudioMB 23:11, 10 July 2007 (UTC)
 * There's no way to know, but I think they're near the country capital, and there are multiple dots because the dot size counts in increments. The 5 dots around Washington DC on the east of the US mean "50" for the US. The Mexican dot is near Mexico City. -- Mikeblas 02:21, 11 July 2007 (UTC)
 * Don't get worked up over (x, y) positions. The objective of the map is only to show the breadth and depth (and by inference, the ratio) of output worldwide. Five yellow dots in the USA territory should be read as: "American farm output was approximately 50% that of China in 2005" and five red dots in the Egypt territory should be read as : "Egyptian farm output was approximately 5% that of China (or 10% that of the USA) in 2005".

 * Shouldn't be better place the dots in the middle of the country? 1)Since this is about agricultural and not about any politic issue, the capital is irrelevant. 2)I believe most of the readers don't know about many countries' capital to figure that out. 3)It could give a wrong impression that represents where the region in the country with more agriculture output is. 4) I think the map will be neater, avoiding, in some cases, dots to be to close to the border or to other countries' dots (like the US and Canada).--ClaudioMB 23:19, 4 October 2007 (UTC)

Clarification about output criteria
I understood that the output is monetary based (because this sentence "top producer (China - $267,000,000,000)"). But it's not clear if the dollar value is based on the production or from currency conversion. For example, I ton of rice produced in China will have the same dollar value as a ton of rice in the US, or the ton of rice in China has a value in the Chinese currency then convert to dollar, what will result that a ton of rice from China and a ton of rice from the US will have different dollar values. I didn't look the source, but I believe this article should clarify that.--ClaudioMB 23:36, 4 October 2007 (UTC)
