One way you can make a graph misleading is by making one of the graphs wider than the other. Another way to make a graph misleading is making a bar a different color than the other ones. You can also make a graph misleading by making one of the bars 3D.
Two graphs that would show this data accurately are line graphs or bar graphs. A line graph would be good because it is good at showing data over time. A bar graph would work because it is good at showing data across categories.
