[Sigia-l] FW: Map-type interfaces for stock exchange

[vila]

Hi all,
 

I have been asked to look into the possibility of using 
an interface similar to the maps of the stock exchange 
where one rectangle represents a quotation. In this type 
of interface, the color of the rectangle indicates wheter 
the value is up/down, the surface indicates the total 
capitalization. Companies are grouped by type of value 
(financial, tech, Industrial
). Here is an example : 
http:// www.smartmoney.com, then click on “Maps - Map of the market”
 
Now here is the question : does anybody have any experience 
implementing such an interface?
Are there easy/cheap components to do it? 
Any ideas of what it would take to develop one such
component in ASP.NET?
 
The use we would make of this kind of map would be somewhat simplified,
 
as all the rectangles would be the same size, and the values displayed 
would probably be discreet (6 different possible values only, coded by
color).
 
Thank you,
