Bar Graphs
A bar graph uses rectangular bars to show data. X-axis (horizontal): categories (subjects, months). Y-axis (vertical): values (number of students, cm of rainfall). Bar height = value. Reading a bar graph: find the bar, go across to the y-axis to read value. Comparing bars: the taller bar has more. Bar graphs are used in newspapers, sports statistics, weather reports.
