+Environment Directed Graphs
+---------------------------
+
+FLAME GPU visualisations provide basic visualisation support for graphs defined within a model's environment.
+
+When configuring the visualisation, graphs to be rendered can be specified by name. Following this, their vertex properties which correspond to the spatial coordinates and :ref:`desired color<static-colors>` should be specified. The graph will then be rendered with the simulation, and will update whenever it is modified via the host API.
