# Graph objects and their properties

Explains the representation of various objects used to render the flow charts and what the properties mean. This ofc from the perspective of the dagre-wrapper.

## node

Sample object:
```json
{
  "labelType":"svg",
  "labelStyle":"",
  "shape":"rect",
  "label":{},
  "labelText":"Test",
  "rx":0,"ry":0,
  "class":"default",
  "style":"",
  "id":"Test",
  "type":"group",
  "padding":15}
```

This is set by the renderer of the diagram and insert the data that the wrapper neds for rendering.
