Using this tool https://www.bottlecaps.de/convert/ (using https://github.com/konclude/rasqal) and manually adding the tokens from rasqal/blob/master/src/sparql_lexer.l we can see a railroad diagram for the grammar in rasqal/master/src/sparql_parser.y copy and paste the EBNF shown bellow on https://www.bottlecaps.de/rr/ui in the tab Edit Grammar then switching to the tab View Diagram.
