-Using the visualiser
-====================
-
-In order to assist with understanding of the state model, the repository includes a simple graph visualiser. The
-visualiser is integrated with the unit test framework and the same domain specific language. It is currently very
-early and the diagrams it produces are not especially beautiful. The intention is to improve it in future releases.
-
-.. image:: visualiser.png
-
-An example of how to use it can be seen in ``src/test/kotlin/contracts/CommercialPaperTests.kt``.
-
-Briefly, define a set of transactions in a group using the same DSL that is used in the unit tests. Here's an example
-of a trade lifecycle using the commercial paper contract
-
-.. container:: codeset
-
-   .. sourcecode:: kotlin
-
-      val group: TransactionGroupDSL<ContractState> = transactionGroupFor() {
-            roots {
-                transaction(900.DOLLARS.CASH `owned by` ALICE label "alice's $900")
-                transaction(someProfits.CASH `owned by` MEGA_CORP_PUBKEY label "some profits")
-            }
-
-            // Some CP is issued onto the ledger by MegaCorp.
-            transaction("Issuance") {
-                output("paper") { PAPER_1 }
-                arg(MEGA_CORP_PUBKEY) { CommercialPaper.Commands.Issue() }
-            }
-
-            // The CP is sold to alice for her $900, $100 less than the face value. At 10% interest after only 7 days,
-            // that sounds a bit too good to be true!
-            transaction("Trade") {
-                input("paper")
-                input("alice's $900")
-                output("borrowed $900") { 900.DOLLARS.CASH `owned by` MEGA_CORP_PUBKEY }
-                output("alice's paper") { "paper".output `owned by` ALICE }
-                arg(ALICE) { Cash.Commands.Move() }
-                arg(MEGA_CORP_PUBKEY) { CommercialPaper.Commands.Move() }
-            }
-
-            // Time passes, and Alice redeem's her CP for $1000, netting a $100 profit. MegaCorp has received $1200
-            // as a single payment from somewhere and uses it to pay Alice off, keeping the remaining $200 as change.
-            transaction("Redemption", redemptionTime) {
-                input("alice's paper")
-                input("some profits")
-
-                output("Alice's profit") { aliceGetsBack.CASH `owned by` ALICE }
-                output("Change") { (someProfits - aliceGetsBack).CASH `owned by` MEGA_CORP_PUBKEY }
-                if (!destroyPaperAtRedemption)
-                    output { "paper".output }
-
-                arg(MEGA_CORP_PUBKEY) { Cash.Commands.Move() }
-                arg(ALICE) { CommercialPaper.Commands.Redeem() }
-            }
-        }
-
-Now you can define a main method in your unit test class that takes the ``TransactionGroupDSL`` object and uses it:
-
-.. container:: codeset
-
-   .. sourcecode:: kotlin
-
-      CommercialPaperTests().trade().visualise()
-
-This will open up a window with the following features:
-
-* The nodes can be dragged around to try and obtain a better layout (an improved layout algorithm will be a future
-  feature).
-* States are rendered as circles. Transactions are small blue squares. Commands are small diamonds.
-* Clicking a state will open up a window that shows its fields.
