They both show a set of data. Line graphs show data over time. Pie graphs show percentages in data.
They should have a title and a key. The values displayed can be percentages or counts or other measures.
Circle graphs are the same as pie charts and data is out in percentages of 360 degrees in sectors of the circle so as the greater the sector then greater is the data
Most people work with percentages in one way or another.
yes, I do
Pie charts are circles that usually show percentages Line graphs are graphs that use lines to show increase/decrease in time Bar graphs are used to show amounts of something♦
well...not sure if you know this but bar graphs already ARE bar graphs, the good news is you don't have to transform them... so half your work is already done XD!
divide top number to bottom
