Template:Flag data is an internal data container not intended to be transcluded directly. It is used indirectly by templates such as flag, flagicon, and others.
This template is transcluded if a flag template is used without the first parameter, or with an empty first parameter. It can be used to place an "invisible" flag icon, as an alternative to using {{noflag}} (which adds a <span> tag with padding at the size of a flag icon), if one item in a list of items with flags shouldn't have a flag icon. For example:
Western Sahara ({{flagicon|}} [[Western Sahara]])
which looks the same as
- Western Sahara (
{{noflag|[[Western Sahara]]}})
Comparison: with and without flag
- Western Sahara (
{{flagicon|}} [[Western Sahara]]) – internally transcludes {{Flag data}} 
Western Sahara ({{flagicon|Western Sahara}} [[Western Sahara]]) – internally transcludes {{Country data Western Sahara}}
