This paper presents a topological and game-theoretic extension of the system of Existential Graphs (EG). EGs were Charles S. Peirce's diagrammatic and iconic approach to logic. By scribing the graphs on assertion spaces of higher dimensions, this extension provides the precise iconic counterpart to the Independence-Friendly (IF) restatement of first-order logic suggested by Hintikka. Consequently, the IF extension completes the project that Peirce initiated: it breaks off from the linear confines of language by diagrams that extend to three dimensions, which Peirce predicted to be necessary and sufficient for the expression of all assertions. Apart from improved ways of performing conceptual modelling on natural-language expressions, this extension reveals the true proportions of Peirce's sign- and model-theoretic thinking in plunging into the notions of identity, negation, continuity and quantification.
