is there some kind of object representation software that you can control remotely through some kind of api?

What it should do is represent objects of various types开发者_如何学Python, but you should be able to control the representation remotely through some network-based api from another application (xml idealy). What I want to do is to have the logic of my application written in C++, where many kinds of "objects" are involved. I'd like to be able to manage these objects visually, but I do not want to write the visual part of the code. So I should have some kind of server written in C++ that will provide the logic for a client that will display the logic. Oh, by the way, this magic visual client should be free software and be able to run in GNU/Linux :D

Depending on how much work you want to do - you could output your object graph as an SVG file, and display that with a good image viewer.

It's hard to suggest anything more without knowing what kind of objects, how many of them, and what the relationships are though.
