📊 Bar Graphs and Line Graphs

A bar graph uses bars of different heights or lengths to compare amounts, like how many pets each classmate has.

Taller bars mean bigger numbers. You can quickly compare categories by looking at which bar is tallest or shortest.

A line graph connects points with a line to show how something changes over time, like the temperature each hour of the day.

Use a bar graph to compare separate categories, and a line graph to show a trend over time.
