英[ˈviʒuəl ˈprəuɡræmiŋ ˈlæŋɡwidʒ]美[ˈvɪʒuəl ˈproˌɡræmɪŋ ˈlæŋɡwɪdʒ]
In computing, a visual programming language (VPL) is any programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation.
