I don’t know how to describe this ... but this is something I that impressed me very much whenever I visit. The "flash" work that have been done by "expert" from the National Geographic is amazing or

--> click on "Multimedia Map and Time Line:" on the right (use IE otherwise you need to install flash)

What I want to mention here is we can construct the "flow" of the application similar to how they construct the interactive "timeline" for the Pearl Harbor attack (zoomable map, interactive timeline, strong and "military-like" color scheme, music, voice ...)

[IRRELEVANT 2] FISHEYE MENU ----- Fish eye menu:

It is quite interesting and easy to use. Try the demo at

Can we apply this on the panel on the left … that Todd is doing (the list that show all items that are loading …) when there are many items that are currently “load” onto the system that can’t be display all within the space provided

 --- Piccolo

Fish eye calenda:

It illustrates the point I raised before: providing more information without loosing the information already provided: be able to zoom in for more details (view tasks for a particular day) without loosing more general information (what is the position of the day with that month)

Presentation tool:

Perhaps we can create “”Zoomable visualization” similar to my idea previously (see “Thought for”

More about the old way of clustering:

No particular “visualization” suggested by the following links is of interest to me, but I thought it would be a good idea to quote them here so that I can refer to it later on if needed

1 thing I learn by reading those links: we can translate the “query” that the user input in into some “visualization” e.g


(find …. Condition A,B,C)

step taken by the program:

Display query visually

--> load the finding … or any relevant steps to retrieve the information for the finding

--> Visualize the finding

• This search engine is powered by the organisation's Visual Net software, and claims to be the 'natural evolution of search'. Web sites are represented by target symbols, clustered by subject.

• WebBrain offers a hybrid approach to searching, in that it supports the use of text queries and directory browsing.
• When I click on a subject, the display will change to show other related categories. The uncomplicated graphics and logical subject hierarchy  easy to use
• Similar to and Kartoo and other that I have mentioned before

Another website that has very similar interface with this page is

Thought for

1. -- atlas of different visualization
· This site contains images of attempts to visually represent and map the World Wide Web. It also provides links and some background information on each of the projects pictured. This site provides an interesting 'snapshot' of how, in the past decade, graphical representations have been utilized in an attempt to make sense of Web resources. Please go to the site for more information
· I like the “Natto View” as it clearly show clearly three dimensions. However, the visualization part is a bit clustered together and doesn’t show the information clearly (the name of the circles)
Good use of the color to show the intensity/frequency on 2D view (good combination of 2D and 3D views)
· WebPath is interesting too with the 3D view that look like the virtual image from the mirror

Thought for

1. color coded
2. "size" coded --> similar to my idea previously (see “Thought for

Thought for

Interesting features:
Interactive: when moving the mouse over the blue dot (represent the common website between 2 search engine, small thumbnail of the website is pop-up)
--> Idea for the project:
The visualization will display “level 1” (the most general view of the finding), onMouseOver individual cluster, “level 2” (more details view will either pop ups or there will be a button that maximize the “level 2” view …. See my prototype figures below)

Informative: small statistic information is provided at the bottom

Convenient: can compare results from different search engines ... this feature can be used to find the best “results” that are listed in both engines (more likely that those results are what user want based on some ranking conditions from both search engines)
--> idea: we can let user set up something like their “favorite” visualize style for the visualization and provide several styles (eg. 2D, 3D visualization, clustering etc rather than have 1 “fixed” visualization like many projects I come across) ... Just the though, havent actually involve on the programming steps so Im not sure whether it is feasible to do so (take into account the time and other resources)

Picture above illustrate the "matrix grid" that provide general thumbnails for several websites ...("finding", or level 1 info). The title on top of each website is a "Rotate" button that when click will maximize or minimize the website according to the previous state of the site (the maximize version of "Yahoo mail" website is illustrate below)

[IRRELEVANT 1] A thought for the project

I haven’t come across anything in data mining visualization that uses gesture yet. However when searching for some ASP.NET articles on Google, I had an idea for the project (not quite for the visualization): using character that “talk” through the step (

In clarification, this is what I have in mind:

For the whole application, the user can choose to be integrated with the application using voice or not (maybe some button for “speak”) (because some user may not be “visual thinkers”)
If they choose “speak”, we can feed the message into the character so that the user can listen to the message instead of “reading” the messages … This can be use to save “screen space” for error messages or any notes we want to display
We can let the user “customize” the characters … a bit of distraction from the real “data analysis” work that they are doing … but a bit wont hurt, would it J?
If they don’t choose “speak”, the normal flow of the application will be used

At the moment the “sitepal” allow “add” to website, I haven’t done much research to see whether they have any “dot net” components that we can use to integrate into the project. I will do it if you think this is a good idea)

For the visualization, from what I researched, all the visualization currently is just a new prettier “look” of what have been developed long time ago. I can’t think of any better way of visualize the data.

Already talk to KL about this idea :)

Though for

Interesting features:

  1. Graphics are good
    1. The most relevant is red
    2. onMouseOver each document (website), the document’s color change to green and links that connect the document to related topics are shown (figures below)


  1. It doesn’t seem to me that it can visualize a lot of information about the finding (eg. Display the frequency dimension, or rank for each individual record of the search result) rather than simple clustering and group by website

Though for -- “flying planet” for music and movie

Interesting feature:

  1. the graphics is good but occupied lots of screen space (picture at 1280*1024 resolution)


  1. Difficult to use and not very informative (screen space use to display info is very limited … the small panel on the left)

Though for

It is quite good

1. Similar topic can be clustered together

2. Can zoom in to have a closer look at each cluster

3. Further interactions are:

a. OnMouseOver each individual record of the search results (the small circles or squares) description and other info is displayed

b. The result and the visualization can be customized (using the tool underneath: day, rank, square/circle, color)

c. By choosing individual record, similar entries that are extracted from the same website are shown


1. When zoom in for further study, the relationship between the cluster under further study and the original search result can be shown (unless user go “Back” or “Top”) à I think it looses some of the meaning of the finding

2. It seems to me that it is only useful for clustering data but not quite as useful for other purposes (eg. Display the frequency dimension, or rank for each individual record of the search result). However, I am not quite sure on this one yet

Official comments

1. Mix review From the New York Times (article is not free anymore)

2. Grokker Complicates Yahoo! Search (drawback) – personal blog (Brad Hill) However, I personally think it is only a drawback for normal search but is ok for data mining purposes
