I love the syntax of railroad diagrams on json.org which are a graphical representation of the BNF language. I haven't found any tools that can produce results as eloquently.
Can anyone identify the tool used to generate these diagrams?

subject Re: Railroad Diagrams on json.orgI drew them with Visio. Creative Docs.NET also works well.

Hello Douglas,
I thoroughly enjoy most things you put out there and the railroad diagrams on json.org are no different. I have been trying to look around for a tool that would generate diagrams nearly as eloquent but have had no luck:
Tool for generating railroad diagram used on json.org
Is there some tool you used to convert the BNF to these diagrams or were they hand crafted?

There was a similar question a few days ago: What is a good tool for creating railroad diagrams?
That question was about how railroad diagrams in the SQLite syntax diagrams were generated. The accepted answer found that the diagrams were generated using a DSL written in Tcl.
Another answer offered a suggestion to use a diagram generator which works off of EBNL grammar.
