What is a DGML file?
Developer file created by Visual Studio, a software development application; saves a directed graph, also called a dependency graph, which shows a visual layout of how source code components depend on one another.
DGML files enables software architects and developers to display high-level views of the relationships in their codebase. For example, if a developer creates class A that depends on class B, then the hierarchical graph will reflect this dependency.
NOTE: DGML files use XML formatting.
