JDK-8173303 introduces a new @moduleGraph tag to include a module graph in the module summary page.

FX modules should have @moduleGraph tag to enable module graph be generated where desirable and consistent with other JDK modules.

JDK-8177057 will enable JDK 9 docs bundle build to include the graph.
