....(Skolem constants) In [6, 4] are found compelling arguments for the intuitions about the use of diagrams in formal reasoning and specially the introduction of heterogeneous reasoning. There exist numerous visual declarative programming languages: VLP [19] VPP [28] LOGraph [10, 11] GrafOLog [15], CUBE [26, 27] SPARCL [34, 35] VEX [8] and Pictorial Janus [18] being the most relevant ones. CUBE is the first visual language to use a three dimensional syntax and of more relevance from our point of view has static polymorphic typing. We think CUBE is an example to follow when ....

....on its computational aspects. We want to focus on simple diagrams with a clear computational interpretation, avoiding as many logical symbols as possible. There exist other visual declarative programming languages like CUBE [12, 13] VEX [7] SPARCL [21, 22] VPP [14] VLP [11] and GrafOLog [8], but none of them uses sets, Venn Euler diagrams and graphical containment as its foundations. The graphical schemes representing conceptual models in [6] do not attempt a formal and systematic visual representation of deductive rules. However they are an inspiration for our future work. The ....
