[Arjen Markus] (8 september 2009) I ran into the article mentioned below, ''How NOT to lie with visualisation'', and thought it would be a good idea to collect references to such articles. Not specifically related to Tcl/Tk, but we do a lot of visualisation, don't we? * How NOT to lie with Visualisation [http://www.research.ibm.com/dx/proceedings/pravda/truevis.htm] * PowerPoint does Rocket Science [http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0001yB], perhaps not directly on the visualisation of data, but still worth reading IMHO. * Edward Tufte has quite a few articles and books on the subject of visualisation. While some of his ideas are quite radical, they should not be dismissed without further thought - again, IMHO. * Was there a proceedings article on [CACTVS]? <>Category Visualization
