Homework #3: Visualization Tools
The goal of this homework is to experience and practice the use of visualization
tools, accustom yourself to seeing data in new ways, discover something
new in data, and think critically about visualizations.
Download the following
visualization tool for examining hard-drive directory tree structures:
That site has more detailed information about how to use the tool.
SequoiaView is based on the TreeMap concept, and lots more can be learned about
TreeMaps here. Use
SequoiaView to examine your hard-drive contents, analyze differences between
SequoiaView and WindowsExplorer, and write a short report.
Report: Write a 2 page report about your findings and about
the visualization tool. You should specifically answer these
- (1 page) Data findings: Describe 2 interesting discoveries you
made about your directories. You must convince me
of your findings. Use pictures to show your claims (e.g. screenshots
of visualizations -- Alt-PrintScrn captures a screenshot that can be pasted
into word processors). Pictures can be on an additional page.
- (1 page) Compare and critique: Answer the following 2
questions about the differences between SequoiaView and WindowsExplorer. Focus
your comparison on the primary views themselves, not the other details of the
user interfaces such as menus or help.
- What types of scenarios are better supported by SequoiaView and why?
- What types of scenarios are better supported by WindowsExplorer and why?
