This script generates three kinds of pages. The user goes first to the top-level page, selects a region, and clicks thebutton. Next they will see the regional index page, which displays all the circles in the given region, with a checkbox by each circle name. After selecting one or more circles by clicking on their checkboxes, the user clicks the button to produce the detail report page, showing the history of the select circles.
See Section 4.2, “General controls on the regional index page” for controls on the regional index page that affect the format of the detail report.
See Section 4.3, “Format of regional page entries” for the format of the bulk of the regional index page.
See Section 4.4, “The detail history report” for a discussion of the format of the final report.
