What does a graph or chart do?

The main functions of a chart are to display data and invite further exploration of a topic. Charts are used in situations where a simple table won’t adequately demonstrate important relationships or patterns between data points.

How is a bar graph different from a chart?

Pie charts represent data in a circle, with “slices” corresponding to percentages of the whole, whereas bar graphs use bars of different lengths to represent data in a more flexible way.

How do you calculate a bar graph?

Draw two perpendicular lines intersecting each other at a point O. The vertical line is the y-axis and the horizontal is the x-axis. Choose a suitable scale to determine the height of each bar. On the horizontal line, draw the bars at equal distance with corresponding heights.
