Examples on Graphical Representation of Data. Example 1: A pie chart is divided into 3 parts with the angles measuring as 2x, 8x, and 10x respectively. Find the value of x in degrees. Solution: We know, the sum of all angles in a pie chart would give 360º as result. ⇒ 2x + 8x + 10x = 360º. ⇒ 20 x = 360º.

Learn how to use graphs to analyse numerical data and display the relation between variables. See different types of graphs, such as line graphs, bar graphs, histograms, frequency polygons and more, with examples and explanations.
6 Inspiring Data Visualization Examples
Data visualization is the process of turning raw data into graphical representations. Visualizations make it easy to communicate trends in data and draw conclusions. When presented with a graph or chart, stakeholders can easily visualize the story the data is telling, rather than try to glean insights from raw data.
2: Graphical Representations of Data
2.3: Histograms, Frequency Polygons, and Time Series Graphs. A histogram is a graphic version of a frequency distribution. The graph consists of bars of equal width drawn adjacent to each other. The horizontal scale represents classes of quantitative data values and the vertical scale represents frequencies. The heights of the bars correspond ...

Data representations
A circle graph (or pie chart) is a circle that is divided into as many sections as there are categories of the qualitative variable. The area of each section represents, for each category, the value of the quantitative data as a fraction of the sum of values. The fractions sum to 1 . Sometimes the section labels include both the category ...

For example, waterfall charts are popular for showing spending or earnings over time. 8. Area Chart. An area chart, or area graph, is a variation on a basic line graph in which the area underneath the line is shaded to represent the total value of each data point. When several data series must be compared on the same graph, stacked area charts ...
Graphical Representation of Data
A bar graph is a type of graphical representation of the data in which bars of uniform width are drawn with equal spacing between them on one axis (x-axis usually), depicting the variable. The values of the variables are represented by the height of the bars. Histograms.

Graphical Representation of Data
Represent the above data by a bar graph. To represent the above data by a bar graph, we first draw a horizontal and a vertical line. Along the x-axis, mark animals and along the y-axis, mark the number of heartbeats per minute.Since six values of the numerical data are given, so we mark six points on the horizontal line at equal distances and draw bars of the same width at these points.
