The function can return null when all parsing attempts fail, but the method signature doesn't indicate this possibility. Consider returning a default empty graph or updating the method signature to make the nullable return explicit.

| return graph ?? new Graph(); |

Catching generic Exception without re-throwing or proper error handling can mask important errors. Consider catching specific exceptions or logging more detailed error information for debugging.

The default case assumes MSAGL format for unknown extensions, which may not be intuitive. Consider adding explicit handling for .msagl extension and making the default case more explicit about fallback behavior.

Support msagl, dot, dmgl. Then we can enrich it to one viewer/editor based on current test01.
