On the Outline or the Design section, you can add a new slide, or use one with enough space for display. Click on Insert > Chart and choose Bar chart.

You can make it horizontal, vertical, or stacked. There are four default sets, or columns, and up to twenty-four rows. Each set would be a category, element, or variable you want to display, and a new row is automatically added after you input data in the last one.

In the Design Section, click on your graph to edit size and position.
