Graphics is an important form to visualize one data from
others. This technique is useful to visualize the target population for any
purpose. For example, I referred to Nepal’s population census 2011 data to get population
values to visualize the number of male household heads from urban areas of Nepal
belonging to the age group of 50 years and above. I used four criteria to filter
and get target population data – male, age group, administrative setting
(urban), and position or role in a household (household head).
An outermost blue circle shows the total population of Nepal,
which is 26,494,504. It is followed by a red circle showing the male population which
is 49 percent of the total population. An inner third yellow circle shows the male
population aged 50 years and above, which is 15 percent of the total male
population. An inner dark ash-colored circle shows the urban male population aged 50
years and above, which is 15 percent of the total males aged 50 years and above.
Lastly, an innermost green circle shows the number of urban male household heads
aged 50 years and above, which is 81 percent of total urban males aged 50 years
and above and 1.9 percent of the total male population in Nepal.
These data are visualized in both stacked Venn
and horizontal hierarchical diagrams in Figures 1 and 2 respectively.

shown in a stacked Venn diagram

household heads aged 50 years and above shown in a horizontally hierarchical diagram
