This wiki page is the central point to collect and structure all information that is needed to implement new features and capabilities to create diagrams with InkScape.
The goal is to create a new plug-in, which has the same (or even better) functionality like Microsoft Visio: create a user interface to create diagrams with a maximum of flexibility and a minimum of work to do.
The Dia project has the same goal, but in my opinion is still a very bad tool: the user interface looks 'ugly', and it just feels bad to work with Dia.
There are a lot of criteria, which make InkScape a good basis to create such TechDrawing capabilites. InkScape: 1. has a huge community, which has already done a great work, and will probably do this in the future 2. has a huge flexibility in creating vector graphics, which is needed to create charts due to resize etc. stuff 3. has a nice Look&Feel; it just feels good to work with InkScape, and it is very simple and powerful to use at the same time. Dia is much harder to use. 4. is a good fundament, to build and implement new software on top of it, for example as new plug-ins
Before implementation phase, we must specically know what the goal is, and how to acieve this goal. A list of requirements is needed. We need to figure out how to desing the use interface: a pure click&drop interface, or a interface where the describes what he wants and InkScape just creates is (WYWIWYG priniciple, like in LateX), or a combination of both.
