InfoZoom: Visual Data Analysis Tool for Efficient Data Exploration

InfoZoom allows users to visually explore, analyze, and search large sets of data that are difficult to view in traditional tables. It presents data using attributes (like weight, height, speed) and objects (such as people, animals), offering wide and compressed views with options for zooming in, out, sorting, and graphing. It enables users to compare different attributes side by side, derive single or combined attribute values, and discover correlations efficiently. The tool is beneficial for conducting population surveys and various data analysis tasks with interactive functionalities like hierarchical sorting and wider attribute viewing.

  1. ICS 105 Research Team How to Use Infozoom ICS 105 Research Team Winter 2002 INFOZOOM

  2. ICS 105 Research Team INFOZOOM What is InfoZoom • InfoZoom allows us to have a visual perception of a large set of data that cannot easily be viewed in a tabulated setting. • Uses of Infozoom: • Explore Data • Analyze Data • Search Data

  3. ICS 105 Research Team INFOZOOM Initial Screen

  4. ICS 105 Research Team INFOZOOM Initial Screen After Loading Data

  5. ICS 105 Research Team INFOZOOM Attributes and Objects

  6. ICS 105 Research Team INFOZOOM Attributes and Objects • Attributes • Weight, height, speed, eye color, age, etc… • Objects • People, Animals, etc…

  7. ICS 105 Research Team INFOZOOM Attributes for Dating Data Set • Here are a list of the attributes used in this data set.

  8. ICS 105 Research Team INFOZOOM Presentation Styles • Wide View • Individual data • Compressed View • All data • Overview • Category

  9. ICS 105 Research Team INFOZOOM Wide View

  10. ICS 105 Research Team INFOZOOM Compressed View

  11. ICS 105 Research Team INFOZOOM Overview

  12. ICS 105 Research Team INFOZOOM Functionality • There are 4 functions with each presentation style • Zooming in • Zooming out • Sorting • Graphing

  13. ICS 105 Research Team INFOZOOM Zooming In • Zooming in focuses on a specific aspect of the database in relation to the rest of the database. • You first select a data and click “Zoom In” and the database will narrow down to all data containing your selection. • Screenshot in Overview

  14. ICS 105 Research Team INFOZOOM Zooming Out • Zooming out takes you back to extracting the selected category to view all values of that category. • Screenshot in Overview

  15. ICS 105 Research Team INFOZOOM Sorting • Sorting is done by click on the arrow( ) next to the attribute name. • It will sort the data from A – Z or in numeric order. By clicking on it again, it will sort in reverse order. • Screenshot in Compressed View

  16. ICS 105 Research Team INFOZOOM Graphing • Graphing allows you to have a graphical view of a certain attribute. • You can do this by clicking on a certain attribute name and clicking on the “Chart” icon. • Different graphing methods are available. • Screenshot in Wide View

  17. ICS 105 Research Team INFOZOOM Changing Attribute Positions • Click on an attribute • Hold and drag up or down • This can help with comparing certain attributes side by side. • Usually helpful in compressed view.

  18. ICS 105 Research Team INFOZOOM Single Derived Attribute • A single derived attribute allows you to form a definite value for a certain attribute. • For instance, this function can help getting the average weight of all the objects in our database.

  19. ICS 105 Research Team INFOZOOM Derived Attribute of 2 Attributes • Deriving an attribute with 2 attributes allows us to get a derived value in relation to a certain attribute. • For instance, the average weight for each hair color can be found. It is also important that you place these attributes side by side, such as weight on top and hair color on bottom and have both these selected.

  20. ICS 105 Research Team INFOZOOM Compressed View Details • Most discoveries regarding direct correlation of attributes can be found in the Compressed View mode. • This is done by sorting(functionality mentioned before) and comparing these attributes to other attributes.

  21. ICS 105 Research Team INFOZOOM Example • This is done by sorting Income and then seeing the relation of income with Spending. • This shows that people with a higher income tend to spend more.

  22. ICS 105 Research Team INFOZOOM Sorting Two Attributes(Hierarchical Sorting) • By sorting attributes we can see two attributes in relation to each other. • This one shows “Gender” per “Income” and done by selecting Income first then Gender. • From this we can see that the steeper slope in “Income” under “Male” indicates males having a generally higher income.

  23. ICS 105 Research Team INFOZOOM Making Lines Wider • You can also increase the height of the attribute displayed. • This may help in comparing certain attributes.

  24. ICS 105 Research Team INFOZOOM Attributes for Population Survey • Attributes for population survey
