My understanding of the software engineering is that sometimes it makes more sense to work with the code in a text editor while sometimes it is graphics which delivers the best performance. So ideally I would like to have a tool which supports both: text and graphics, without sacrificing any of the two ways to look at the code. That ideal tool would also provide a smooth and integrated way to switch between the views of the same code. Is there such a tool on the market? I have not found any so far. There are generic engineering graphics tools like Dia or MS Visio which are very good at what they are designed for. They can help at some stages but it is hard to use them when there are frequent changes. There are tools which support a design stage - e.g. UML oriented tools - but it is hardly ever possible to use them on a lower level. There are code generators but the generated code in many case is not really for reading it. There are domain specific graphics oriented tools - like DRAKON - and I cannot use them for my general purpose projects. They usually sacrifice the text and concentrate on drawing or even do not provide access to the text at all.
So if a suitable tool does not exist why not to develop it? Basically such a tool would make it possible to look at any existing project via two views, together with ability to edit any of them with an automatic synchronization between each other. My research is about how to do it for Python and mostly in Python.
