5. 1. Charts, graphs, and tables provide a great deal of visual appeal.
2. They allow users to quickly spot trends, examine pronounced data, and
see an actual picture. This power and appeal makes a “picture worth a
thousand words.”
3. In Business Presentation, charts, graphs, and tables can be used to
represent data, illustrate important patterns or relationships, and
observe changes as data is altered.

10. 1. A pie chart divides a circle into slices to represent a data series
2. The chart depicts each pie slice in a different color for easy recognition
of how the individual slice relates to the greater whole.
3. Pie charts work best when you're charting only one data series, when
none of your data are negative, when your data features no zero values
and when you have seven values or fewer.

12. 1. Bar charts are essentially horizontal column charts.
2. A bar chart organizes the categories along the vertical axis and
the values along the horizontal axis.
3. Horizontal bars stretch left to right across the chart to plot the
data.
4. Bar charts are excellent for charting multiple values over
extended durations, with colored bars representing each value.

14. 1. The chart's horizontal axis presents the
categories being charted, while the vertical axis
shows the charted values.
2. Vertical columns of differing colors rise from
the horizontal axis to visually represent the
desired data.
3. The simple presentation and colored columns
make for easy visual comparisons.

16. 1. Line charts use one or more horizontal lines to visually
depict data points.
2. The chart distributes categories evenly along the horizontal axis
and values evenly along the vertical axis.
3. The horizontal line connects the plotted points, providing a clear
picture of data trends.
4. Line charts work best when presenting data over evenly
distributed time intervals.

18. 1. An area chart or area graph displays graphically quantitive data. It
is based on the line chart.
2. Area charts are used to represent cumulated totals using
numbers or percentages (stacked area charts in this case) over time.
3. Use the area chart for showing trends over time among related
attributes.
4. The area chart is like the plot chart except that the area below
the plotted line is filled in with color to indicate volume.

20. 1. An X-Y graph, also called a coordinate graph or scatter plot, is a
graph that shows different ordered pairs on an X-Y axis (Cartesian
coordinate system).
2. X-Y graphs are used to look at and find patterns in sets of data and
to plot mathematical formulas.
3. The points on the graph may form a straight line or a curved line,
and may be connected with a line or a bunch of random dots
scattered all over the place.

24. SELECTING THE RIGHT
VISUAL
You are preparing the annual report foryour
company.
What is the appropriate visual (a table, a pie chart, a
barchart, a line graph,) to illustrate each of the
following types of information?
1. Data on annual sales for the past 20 years.
 a table or a line graph
2. Comparison of the sales, product by product (there are four
different products), for this year and last year.
 a bar chart
3. Comparison of your company’s sales figures with sales
figures of three competing companies over the past five
years
 a table or a line chart

25. Charts are a good way to visually represent data. Once created, charts can
be merged with other technology products to convey an idea, demonstrate
content knowledge, and communicate findings.
Remember,
“a picture is worth a
thousand words…”
