B4J Question How to generate a vector image of any size ? Crossplatformly

HI, All

There is an idea to make an app that after collecting data can auto-generate the diagram of some vector format, like:



Any ideas how to generate such circuit diagrams ?
Diagram can be of biiiiiig size, depending on the list of objects... Some text on them should be readable, so the whole picture can be large also...


Do we have any crossplatform class to generate vector pictures ?
And, actually, the objects are to be clickable for edit of connections, names...
