This document provides information about different types of charts used to visualize data including pie charts, bar graphs, double bar graphs, and histograms. It explains that pie charts display data in a circular format, bar graphs use bars to represent data with space between them, double bar graphs have two sets of bars to show data over time, and histograms use class intervals and frequency to represent data distribution with red lines indicating gaps between intervals.

2. DATA HANDLING.
Pie Chart
 A Pie Chart is a chart which display a
data in a circle. For example-

3.  A Bar Graph is a graph which displays a data
with the use of bar. It is very useful to
represent big data.
 There is also between the bars in order to
represent data properly.
 Frequency of the data is also necessary.

4. DOUBLE BAR GRAPH
• A Double bar graph is a graph which also
displays a data with the help of two bars in
one graph.
• There is also space between the bars of
graph.
• To draw this bar we need the frequency of
given data with the time also.

5. HISTOGRAM.
 A Histogram is a graph in which
there is no difference between the
bars of the table and data is
displayed with the help of class
interval. The data displayed in such a
graphical manner is said to be a
Histogram.
 Frequency is given with class
interval.
 Red Wavy Line is also used between
the class interval to show that there
is no data between this to this class
interval.
