In general, graphs compare two variables. A scatter plot can compare a third variable because the quantity of dots gives additional information from just the two axes. A color coded scatter plot can give even more information because each colored dot can be distinct.
Adding more colors can ad more distinct categories.
Color coding any type of graph, such as pie chart, bar graph or multi-line two axis graphs can also represent more than two distinct categories.
A bar graph
The line and the bar graph is used to describe a graph that compares two sets of data.

Scatter plot
Any data consisting of two sets of quantitative measures on a set of objects. Although the horizontal axis is often used for categories, the graph is then not a Cartesian graph.Any data consisting of two sets of quantitative measures on a set of objects.

A bar graph
A comparing graph is a graph that compares number to see if they similar or different.
The line and the bar graph is used to describe a graph that compares two sets of data.
a line graph
I would suggest a bar graph. Depending on the topic and how you want to show it you could also use a pie chart.
line graph
A scatter graph.
a bar graph is just a graph but a double bar graph compares 2 things!
A pie chart or graph presents data in this way.
A pie chart
A bar graph.
A bar graph compares the height of the bar to the amount represented.
