Example: Creating a Simple Organizational Chart

The following example creates a simple organizational chart with two levels. It consists of five rectangle shapes and four connectors that connect the boxes on the second level with the root box on the first level.

Sample Organigram

The method getRemoteServiceManager() that is used in the example connects to the office. The First Steps discussed this method. First an empty drawing document is loaded and retrieves the draw page object of slide number 1 to find the page dimensions. Then the organigram data is prepared and the shape sizes are calculated. The shapes are added in a for loop that iterates over the organigram data, and connectors are added for all shapes on the second level of the organigram.
