I need a simple 2D room planner for Web. It's only to design a room, without decoration. Only for design walls, inform where doors and windows will be, change the floor, etc.
After ends of designing, user can click on a button labeled "Save" and It can be save in a JSON file or this information (JSON) can returned back below.
There is a similar project at [url removed, login to view], but the 3D it is unecessary.
