COMPSTAT’2004 Symposium ©c Physica-Verlag/Springer 2004 LINE MOSAIC PLOT: ALGORITHM AND IMPLEMENTATION

Abstract: Conventional mosaic plot is to graphically represent contingency tables by tiles whose size is proportional to the cell count. The plot is infor-mative when we are well trained reading this. This paper introduces a new approach for mosaic plot called linear mosaic plot which uses lines instead of tiles to represent the size of the cells in contingency tables. We also present a general straightforward algorithm to construct the plot directly from the data set. We demonstrate the effectiveness of this tool for visual inference using a real data set.
