The tag tree graph below shows the number of times the GEDCOM tag(-sequence) was encountered. Filled circles can be clicked to show the sub-tags.
The red circles (83.3%) are valid tag-sequences under the GEDCOM 5.5 grammar (also available as tag tree), grey circles (16.6%) are invalid tag-sequences or tag-sequences with user-defined tags. This visualisation aspect is not completely accurate as not all GEDCOM files are version 5.5 (the actual version wasn't taken into account, but from all processed GEDCOM files 92% identified itself as GEDCOM 5.5 and 4% as GEDCOM 5.5.1).
