I came across a very interesting site called Flags by Colours, which displays Flags of various Countries as a Pie chart. Each sector of the pie chart is proportional to the area of the colour on the respective country's flag.
So try to find out India's flag. I could do it in first attempt. No cheating please. (As mouse shows tooltip). And also find other country's flag after finding India's Flag. Jai Hind !!
"Flags of countries fetched from Wikipedia (as of 26th May 2007) are analysed by a custom made python script to calculate the proportions of colours on each of them. That is then translated on to a piechart using another python script. The proportions of colours on all unique flags are used to finally generate a piechart of proportions of colours for all the flags combined"
