Sector graph Circle graph Pie chart Use sectors of a circle to show sizes of parts

Why circle graph/pie chart? The circle provides a visual concept of the whole (100%). Circle graphs/pie charts are simple to use.

Sector graphs are used when there are no more than six components only—otherwise, the resulting picture will be too complex to understand.

Title Sectors Six types of sports are shown on the sector graph Key Graph Title – the title tells what the graph is representing. Sectors – Each sector is one part of the whole circle. It represents a particular category. Sector Labels – Each label tells what the sector represents. Labels 20% Percentage Sector graph or pie chart Sector graphs are used when there are no more than six components.
