## New diagrams in 8.5
|

With version 8.4 class diagrams have got some new features, bug fixes and documentation. Another new feature in 8.4 is the new diagram type, state diagrams.
|
||||
With version 8.5 there are some bug fixes and enhancements, plus a new diagram type, entity relationship diagrams.

# Cluster handling
|
||||
|
||||
Dagre does not support edges between nodes and clusters or between clusters to other clusters. In order to remedy this shortcoming the dagre wrapper implements a few work-arounds.
|
||||
|
||||
In the diagram below there are two clusters and there are no edges to nodes outside the own cluster.
|
||||
|
||||
```mermaid
|
||||
flowchart
|
||||
subgraph C1
|
||||
a --> b
|
||||
end
|
||||
subgraph C2
|
||||
c
|
||||
end
|
||||
C1 --> C2
|
||||
```
|
||||
|
||||
In this case the dagre-wrapper will transform the graph to the graph below.
|
||||
```mermaid
|
||||
flowchart
|
||||
C1 --> C2
|
||||
```
|
||||
|
||||
The new nodes C1 and C2 are a special type of nodes, clusterNodes. ClusterNodes have have the nodes in the cluster including the cluster attached in a graph object.
|
||||
|
||||
When rendering this diagram it it beeing rendered recursivly. The diagram is rendered by the dagre-mermaid:render function which in turn will be used to render the node C1 and the node C2. The result of those renderings will be inserted as nodes in the "root" diagram. With this recursive approach it would be possible to have different layout direction for each cluster.
|
||||
|
||||
```
|
||||
{ clusterNode: true, graph }
|
||||
```
|
||||
*Data for a clusterNode*
|
||||
|
||||
When a cluster has edges to or from some of its nodes leading outside the cluster the approach of recursive rendering can not be used as the layout of the graph needs to take responsibility for nodes outside of the cluster.
|
||||
|
||||
```mermaid
|
||||
flowchart
|
||||
subgraph C1
|
||||
a
|
||||
end
|
||||
subgraph C2
|
||||
b
|
||||
end
|
||||
a --> C2
|
||||
```
|
||||
|
||||
To handle this case a special type of edge is inserted. The edge to/from the cluster is replaced with an edge to/from a node in the cluster which is tagged with toCluster/fromCluster. When rendering this edge the intersection between the edge and the border of the cluster is calculated making the edge start/stop there. In practice this renders like an an edge to/from the cluster.
|
||||
|
||||
In the diagram above the root diagram would be rendered with C1 whereas C2 would be rendered recursively.
|
||||
|
||||
Of these two approaches the top one renders better and is used when possible. When this is not possible, ie an edge is added crossing the border the non recursive approach is used.
