```
:dot COMMAND [FORMULA]
```
Execute and show a dot visualisation.
The following dot visualisation commands are available:

* `operations` - Operation Call Graph: Shows the call graph of a classical B model
* `event_hierarchy` - Event Hierarchy: Shows the event hierarchy of an Event-B model
* `state_space` - State Space: Show state space
* `state_space_sfdp` - State Space (Fast): Show state space (fast)
* `current_state` - Current State in State Space: Show current state and successors in state space
* `history` - Path to Current State: Show a path leading to current state
* `signature_merge` - Signature Merge: Show signature-merged reduced state space
* `dfa_merge` - DFA Merge: Show state space as deterministic automaton (DFA)
* `transition_diagram` - State Space Expression Projection...: Project state space onto expression values and show transition diagram
* `enable_graph` - Enable Graph: Show enabling graph of events
* `state_as_graph` - Current State as Graph: Show values in current state as a graph
* `custom_graph` - Customized Current State as Graph: Show values in current state as a graph using CUSTOM_GRAPH_EDGES
* `expr_as_graph` - (Relational) Expression as Graph...: Show (relational) expression value as a graph
* `formula_tree` - Custom Predicate/Expression Formula Tree...: Show predicate/expressions and sub-formulas as a tree
* `invariant` - Invariant Formula Tree: Show invariant as a formula tree
* `properties` - Properties Formula Tree: Show properties as a formula tree
* `assertions` - Assertions Formula Tree: Show assertions as a formula tree
* `deadlock` - Deadlock Formula Tree: Show deadlocking status as a formula tree
* `goal` - Goal Formula Tree: Show GOAL as a formula tree
* `dependence_graph` - Dependence Graph: Show dependence graph of events
* `variable_modification_graph` - Variable Read/Write Graph: Show variable modification by operations and reading in guards
