There is also an open source utility for disk space visualization called WinDirStat. There is also this relevant question on SO:Īlso, implementation in TypeScript is here. This function is further discussed below: procedure squarify(list of real children, list of real row, real w) Rectangles, given the length of the side along which they are to be Theįunctionworst() gives the highest aspect ratio of a list of ![]() List row contains the rectangles that is currently being laid out. Numbers, representing the areas of the children to be laid out. ![]() The input of squarify() is basically a list of real To keep the description simple, we use some list notation: ++ isĬoncatenation of lists, is the list containing element x, and Remaining subrectangle in which the current row is placed and aįunction layoutrow() that adds a new row of children to the rectangle. It supports aįunction width() that gives the length of the shortest side of the We assume a datatype Rectangle that contains the layout during theĬomputation and is global to the procedure squarify. To the row will improve the layout of the current row or not. This decision depends only on whether adding a rectangle Either the rectangle is added to the current row, or theĬurrent row is fixed and a new row is started in the remaining When a rectangle is processed, a decision is made between twoĪlternatives. Procedure lays out the rectangles in horizontal and vertical rows. The proposed algorithm is recursive in nature.įollowing the example, we present our algorithm for the layout of theĬhildren in one rectangle as a recursive procedure squarify. Its description and discussion of related issues can be found in this paper by Mark Bruls, Kees Huizing, and Jarke J. The algoritm you are looking for is called Squarified Treemap Algorithm.
