Below is a Gantt Chart of a proposed development schedule. Although the times and dates are arbritrary, the chart accurately describes tasks which must be completed and suggests (perhaps more importantly) a squence of events.

On the Left are the tasks and a target for the suggest number of days each task should take. On the right is a bar indicating the time graphically and the resources which must be available for each corresponding task on the left. You can "click-drag" the right window and scroll up and down the list. If you scroll over the task, the line will be highlighted - or - alternatively view the pdf version.
