Bar graphs and pictographs
You have counted how many of each kind there are. How can a picture show those counts so anyone sees the biggest at a glance and can still read the exact numbers?

What this area is about
A list of votes or a tally holds every count, but nobody can see the winner by looking at it. A picture graph and a bar graph both give each category its own row or bar, so a longer one means more. A picture graph shows the count with small pictures. A bar graph shows it with a solid bar and a number scale beside it.
How these fit together
Picture graphs. Picture graphs and their key draws one picture per thing and uses a key to say what one picture stands for. Scaled picture graphs lets one picture stand for several things, say 10, so half a picture stands for half of that, 5.
Bar graphs. Reading a bar graph gets a count out of a bar by following its end across to the scale. Making bar graphs goes the other way, from a table of counts to bars of the right height with a labeled scale.
A path through it
Picture graphs and their key come before scaled picture graphs. Read a bar graph before you make one. The two pairs can be taken in either order, though most readers meet pictures first.
Bars return in histograms, where they stand for number ranges, and in the segmented bar graphs of association in a two-way table.
