40,000 interactive nodes in a browser!
Enterprise data visualization with InfiView
A prominent network corporation asked us to demo how InfiView can present in a browser, a large data set, stored on a remote server, while enabling users interaction.
InfiView is an Ajax Framework for Data Visualization (100% built in Bindows).
* Display a graphical representation of a computer network with 40,000 nodes representing various network elements (servers, routers) connected with links
* Show two viewports, each showing different parts of the data
* Each viewport can be independently panned and zoomed
* Network elements can be moved (drag with the mouse)
* New links can be created
* Links can be created between nodes in different viewports
The data for the network resides in a server-side database. The server exposes this data through a JSON web service interface.
The application takes advantage of InfiView’s memory management technology so that only the part of the network that is visible on the screen needs to be transferred over the network. As the user pans or zooms the viewport, InfiView intelligently fetches more data from the server as needed (and at the same time, releases unused data from memory).
The backend holds the network database, including the positions and properties of all the nodes, and the links between the nodes. It uses a spatial index to efficiently find all the nodes within a certain rectangle. The demo backend is implemented using the Grails framework.
