11. Pie chart A type of graph in which circle is divided into sectors that each represent a proportion of the whole. It is idea for showing fractional relations. However, it is a difficult to prepare and to understand if the segments or percentages are to small, to or too similar.

12. Advantages of a pie chart A pie chart presents data as a simple and easy-to-understand picture. It can be an effective communication tool for even an uninformed audience, because it represents data visually as a fractional part of a whole. Readers or audiences see a data comparison at a glance, enabling them to make an immediate analysis or to understand information quickly. This type of data visualization chart removes the need for readers to examine or measure underlying numbers themselves. You can also manipulate pieces of data in the pie circle to emphasize points you want to make.

13. DISADVANTAGES OF A PIE CHART A pie chart becomes less effective if it uses too many pieces of data. For example, a chart with four slices is easy to read; one with more than 10 becomes less so, especially if it contains many similarly sized slices. Adding data labels and numbers may not help here, as they themselves may become crowded and hard to read. This kind of chart only represents one data set -- you need a series to compare multiple sets. This may make it more difficult for readers to analyze and assimilate information quickly. Comparing data slices in a circle also has its problems, because the reader has to factor in angles and compare non-adjacent slices. Data manipulation within the chart's design may lead readers to draw inaccurate conclusions or to make decisions based on visual impact rather than data analysis.

14. Bar chart A diagram in which the numerical values of variables are represented by the height or length of lines or rectangular of equal width. It is a simple and easy to construct and is used to make comparisons of two or more data. It has a zero base and the data is plotted with the help of horizontal or vertical bars. The length of the bar represents the amount in terms of percentages, calories, grams , mean, etc.

15. Advantages of bar chart show each data category in a frequency distribution display relative numbers or proportions of multiple categories summarize a large data set in visual form clarify trends better than do tables estimate key values at a glance permit a visual check of the accuracy and reasonableness of calculations be easily understood due to widespread use in business and the media

16. Disadvantages of bar chart require additional explanation be easily manipulated to yield false impressions fail to reveal key assumptions, causes, effects, or patterns

19. Advantages of tree chart Are simple to understand and interpret. People are able to understand decision tree models after a brief explanation. Have value even with little hard data. Important insights can be generated based on experts describing a situation (its alternatives, probabilities, and costs) and their preferences for outcomes. Allow the addition of new possible scenarios Help determine worst, best and expected values for different scenarios Use a white box model. If a given result is provided by a model. Can be combined with other decision techniques.

20. Disadvantages of tree chart For data including categorical variables with different number of levels, information gain in decision trees are biased in favor of those attributes with more levels. Calculations can get very complex particularly if many values are uncertain and/or if many outcomes are linked.

21. Strip tease chart  Striptease chart: Strip chart has some peculiar characteristics such as (1) it enables speakers to present the information step by step; (2) it increases the interest and imagination of the audience; (3) the information on the chart is covered with thin paper strips applied either by wax, tape or sticky substance or pins; (4) as the speaker wishes to visually reinforce a point with words or symbols, he removes the appropriate strip or paper; and (5) it produces interest and it increases learning and aids recall.
