This log is going to show what I had to do to construct the visualization.
First, I have to formulate the question by performing the following steps:
1) download one or more databases from U.S. Department of Labor's Bureau of Labor Statistics
2) pose a question that should be expressed in that data
The databases we were directed to were a set of Occupation Employment and Wage Estimates. I selected the 2002 - 2006 "State Cross-Industry estimates." These databases contains the total number of persons employed and their average annual salaries by occupation within each state.
The question I would like to ask is "Is there a relationship between the growth of the computer and mathematical science occupation and a higher overall average annual salary?" The "growth of the computer and mathematical science occupation" shall be measured by indicating an increase in total persons employed in the occupation.
Next, I have to do the following:
- format of the dataset
- select the visualization system
- design and perform the transformations required to work with the visualization system
