Sankey Diagram
在我苦思好久怎麼解決表現relationship問題的時候
偉大的Chris提出了一個超棒的想法：Sankey Diagram
剛好可以解決我的問題！！！
然後他說我的東西結合Sankey Diagram大概就像Theme River結合Sankey Diagram
應該還滿有價值的(撒花花~~)
但是我最好不要讓它變得太application
朝這兩個圖的概念結合起來應該是比較可行的方向！！(筆記)

fetch related tags in different days of del.icio.us
For my study, I just write a small PHP program, which shows the relation of a specific tag in different days.
the php file could be download from here
The return format is as follow
<data name="Queried Tag" >
<date time="YYYYMMDD" total="number of tag at that date">
<tag name="related tag" count="number of co-occurence"/>
</date>
</data>
Actually it directly parse the info on the del.icio.us page.
To avoid being banned by del.icio.us, the program would sleep 1 second for each 10 pages.
Thanks for the HTML parser written by S.C.Chen.
For more detailed info, please visited the SourceForge
Also, there's a simple chinese tutorial over here

I would also think of adding the count of the related tag of a specific day. However, instead of really go through all pages until find the day, I have no good idea of fetching those information.
If any of you have a better solution, please help me, Thanks!!!!

Difference between InfoVis and HCI
HCI focus on "New interaction skill"
Infovis uses tranditional interaction, but what may be more important is "New Layout"
User study is really important for HCI, and it also helps a lot on InfoVis.
(But I think they're not as important as that in HCI)
