I need to implement a module into an aplication that lets the user draw a grid.
The grid is made out of rectangles of any shape and size, but they have to be rectangles. Imagine a prism or a mosaic. A big quare containing many rectangles. The user needs to be able to create any kind of rectangle withing that square.
Is there such a library in existance? It can be anything. Canvas, svg, regular divs, whatever.
