Graphical Methods for Presenting Statistical Data: Progress and Problems

Statistical maps are of great interest both to cartographers and to statisti cians. Cartographers and geographers consider such maps as a very important cate gory of thematic maps. Statisticians view them as applications of the graphicalstatistical method to the special case in which the data to be graphed are detailed geographically. Professor Jenks and Professor Robinson have discussed statistical maps from the first viewpoint. I shall discuss them from the second. In so doing I shall draw largely from the conclusions of a meeting on geographical statistical methods held recently at the ^Oth session of the International Statistical Insti tute in Warsaw 1_/ and from the experience gained from an exhibition of automated statistical graphs and of new graphical symbols held at that session.
