Delete the network visualiser sample. It's very old and the build is strange and breaks in odd ways when Gradle runs in parallel. We haven't used it for a long time and have better demos these days anyway

# Network Visualiser
|
|
||||||
|
|
||||||
This package contains a network visualiser that uses a simulation to visualise the interaction and messages between nodes on the Corda network.
|
|
||||||
|
|
||||||
Please see the either the [online documentation](https://docs.corda.net/network-simulator.html) for more info on the network visualiser, or the [included offline version](../../docs/build/html/network-simulator.html).
|
|
||||||
|
|
||||||
From the root directory of the repository, run it like this (Windows):
|
|
||||||
|
|
||||||
gradle samples:network-visualiser:run
|
|
||||||
|
|
||||||
or (Mac / Unix)
|
|
||||||
|
|
||||||
./gradlew samples:network-visualiser:run
