Creating Substitution Key-Value Pairs for D3 Visualization

You want to create centralized substitution values for common or redundant parameter values that can be used for dashboard situations such as:

• Displaying six gauge controls on one page and six pie controls on other in 3 * 2 format. The DashboardLayout section is the same for each dashboard but the widget sections are different and require two separate JSON files.
• Updating or overriding default or common styles for every widget or an entire dashboard page.
• If the same data is represented in two different widgets, duplication of information can be simplified. For example, a pie control and a bar chart can have the same data provider information but different widget sections. The JSON configuration file can be simplified by using substitutions for the data provider sections.
