I think on the problem with the villages the one with one picture and $100$ next to it because its easier than counting all the people. on the flag one the grid is the best way instead of drawing $100$ flags.
From Vincent & Salambô at Lycée Henri Matisse in France we had;
For the first question about the population of the village, we choose the drawing with the heads organized in a square rather than the drawing with the head scrambled. Because in a square of side $10$ we understand easily that the area is $100$. Thus to symbolise $100$ people the best is to draw a square of side $10$ little heads.

In the first graph with the people, I think the first one is best because its meaning is easiest to decipher. In the one with flags, I think the second graph is clearest because it is not as messy as the first one.
From Dubai in UAE we had a response from Amatuliah at Alameen Private School who wrote that for question $1$ the first way was best and for question $2$ the third one was best.
What do you think?
