The planning for an application that uses a Custom Visualization item follows all recommendations for planning a BIRT application. Before using a Custom Visualization item in a BIRT application, identify what data in the application you want to visualize and what type of visualization you want to use. After you choose the content and data to display in the Custom Visualization item, select the visualization template to display this information. Verify that user permissions, such as file permissions necessary to view BIRT documents or BIRT data objects, enable target users to access this information. Then consider how you want users to interact with the Custom Visualization item. For example, decide whether you filter the displayed data for the user or you enable users to select filter values with data selection.
