Hey, really good work. Much appreciated. We are now moving away from svgDraw (based on d3) to a newer rendering engine based on dagre-wrapper.
Can you add similar changes in the class_box (src/dagre-wrapper/nodes.js). as in the next release, we will shift class diagrams to this rendering engine.
Once this is done, we will be happy to merge this PR.

It's done ! Let me know if something is wrongly done.

[Xstoudi]

Just to be sure, are you aware that dagre seems to indicate it's deprecated?

For some reason, this currently only works in specific cases:

classDiagram
  class Person {
  String name$
  name : String$
  name$ : String
  name$
  }
  Person: int age$
  Person: age$

classDiagram
  class Person {
    String name$
    name : String$
    name$ : String
    name$
  }
  Person: int age$
  Person: age$

Why doesn't it just check, if the line is a field and ends with a $ or *? It currently seems to do some shenanigans, that only allows it to work if the field is formatted in a specific way:
First Character may be one of + # - ~, one word without any special character, a whitespace, one word without any special character, ends with $ or *
As RegEx something like this: (\+|-|~|#)?[a-zA-Z0-9] [a-zA-Z0-9](\$|\*)

It should be more like this: .*(\$|\*)
