To begin a chart right click on the slide and choose a slide layout.
There are a few that will provide a chart. Select the one that appeals
to you. Once the slide has the chart option on it, double click on the
autoshape and the graph generator will show itself. Right click on the
shape and locate chart type. Chart types and chart subtypes are on one
page. Data can be placed in the speadsheet-like data section. Other
formatting and labelling can be done around here also.
