A common Web development task is showing large data sets. To navigate through the dataset, the user is forced to reload the entire Web page, which makes data browsing a slow process. The example we will build in this chapter is a graph of the time the sun rises and sets for different cities. It will also include a table showing the data from which it's built; this data browsing is especially handicapped by the constant reload process. The actual graph generation is a slow process, and because it shows data for the entire year, it doesn't need to be updated as you look through the data month by month. In this chapter, I will show how you can use the AJAX technique of subpages to greatly speed up data browsing.
