Chapter 22. Scripted Client-Side Graphics
Next, the chapter covers vector-graphics technologies, which provide a far more powerful client-side drawing capability. The ability to dynamically generate sophisticated graphics on the client-side is important for several reasons:
The code used to produce graphics on the client side is typically much smaller than the images themselves, creating a substantial bandwidth savings.
Dynamically generating graphics from real-time data uses a lot of CPU cycles. Offloading this task to the client (which usually has CPU power to spare) reduces the load on the server, potentially saving on hardware costs.
Generating graphics on the client is consistent with the Ajax application architecture in which servers provide data and clients manage the presentation of that data.
