Imagine you want to show your friends how much taller your pet puppy grew every single week this summer. If you used a round pie chart, it would look like your puppy is made of slices of pizza!
Picking the wrong graph scrambles your message, but picking the right one makes the hidden patterns in your data instantly jump out.
How do you know which graph to pick before you even start drawing?

The Four Graph Champions

In math and science, you will rely on four main champions: bar graphs, line graphs, pie charts, and line plots.
Each graph is built for a specific kind of data and a specific job.
What makes a bar graph the ideal choice when your data lives in separate buckets?

Comparing Groups: Bar Graphs

A bar graph uses separate rectangular bars to compare amounts across different categories, known as categorical data.
Because categories like 'Soccer', 'Basketball', and 'Swimming' are completely separate things, their bars stand with spaces between them.
When you want to compare two sub-groups side by side—such as boys versus girls or Grade 5 versus Grade 6—you use a double bar graph.
