Assignment 2 (20 points)
Name: _________________________
· Pick two (2) charts of different chart type (Categorical, Hierarchical, Relational, Temporal and Spatial) [Do not choose bar, pie and line charts)
· For each use a tool that can be used to create the selected chart. Use a different tool to create each chart.
· For each chart, write how to read the chart and what to look for.
Delivery: A word file with the following information:
1. 2 Charts
2. 2 Screenshots of the charts in development with the tools selected.
3. Paragraphs detailing how to read each chart and what to look for.
One of the charts I have picked is pyramid chart of hierarchical chart type which I have created using an Infogr.am tool. When reading the chart, one has to see the multiple layers that connote a chain of command or responsibility. The employees are ranked at different levels within the organization and each level is one above the other. When reading the pyramid chart, what to look for is the organizational structure. In a pyramid organizational chart, every entity in the organization, except one-the CEO, is subordinate to a single other entity. In an organization, the organizational hierarchy consists of a singular source of power at the top with subsequent levels of power beneath them. Imperatively, the pyramid chart is very useful in case one wants to get a snapshot of the employees’ place and level or responsibility in the organizational structure.
The other chart that I have picked is radar chart o the categorical chart type which I have created using excel. The chart graphically displays multivariate data in the form of a two-dimensional chart. The quantitative variables such as the Math and English performances represented on the axes start from the same point. When reading a radar chart, one compares multiple quantitative variables. What to look for when reading a radar chart is a polar grid. This will give an easy way to visualize the multivariate data o performances of the two subjects among the students.
