🧮 Step-by-Step Rules for Drawing a Pie Chart

1. Collect and Organize Your Data

• Make sure your data categories are mutually exclusive and represent parts of a whole.

• Total all values to get the sum.

2. Convert Data to Angles

Each slice of the pie chart corresponds to an angle out of 360°:

• Use the formula:

$$\text{Angle}=\left(\frac{\text{Category Value}}{\text{Total Value}}\right)\times {360}^{\circ }\backslash text\{Angle\}\; =\; \backslash left(\; \backslash frac\{\backslash text\{Category\; Value\}\}\{\backslash text\{Total\; Value\}\}\; \backslash right)\; \backslash times\; 360^\backslash circ$$

• This ensures each sector is proportional to its data value.

3. Draw the Circle and Radius

• Use a compass to draw a neat circle.

• Mark the center and draw a radius—this will be your starting line for measuring angles.

4. Measure and Draw Each Sector

• Use a protractor to measure each angle from the radius.

• Draw each sector in sequence, rotating the protractor from the last line drawn.

5. Label and Color

• Add labels or a legend to identify each sector.

• Use distinct colors or patterns to differentiate categories.

6. Add Title and Key

• Give your chart a clear title.

• Include a key if labels don’t fit inside the chart.

✅ Pro Tips

• Avoid using more than 5–6 slices—too many sectors can make the chart hard to read.

• Use a bar chart instea
