Installation

1. Install package
2. Add @EnableMeshineryDrawing to your SpringApplication

Endpoints

There are serveral endpoints which different formats of the current computed graph. All endpoints can return the complete or part of the graph (called subgraphs). These subgraphs are recognized by a MeshineryTask property called graph.subgraph

The general pattern is

url:port/draw/{format}/{optional:subgraph}

Format: Png

Returns a complete image

Format: Mermaid

Returns a txt file with a mermaid.js description of the graph.

This file can be provided via url to the following Grafana Plugin which can displays the graph and apply metrics on them. Url needs to be something like this (if run via docker-compose) http://10.0.2.15:8080/draw/mermaid

Customization beans

The configuration will pickup EdgeCustomizer, NodeCustomizer and GraphCustomizer beans and provide them to the MeshineryDrawer. You can override these beans and style the graph by yourself.
