Pie/Bar Chart
This interface allows the
user to generate a pie or a bar chart over some attributes. A data analysis that can be done with these charts is
the comparison between two or more compatible attributes.
For example, using data from some districts, it is possible to make a comparison of the
income distribution using the attributes that indicate the salary
ranges based on the minimum salary. The salaries ranges varies from 2-5, 5-10,10-15,15-20, >20 as showed below.
