I think it&#8217;s especially dysfunctional, for several reasons<\/strong>:<\/p>\n<ul>\n<li>The pie chart has been separated into four small infographics. But it&#8217;s hard to\u00a0extract\u00a0the information from these infographics, as\u00a0one has to <strong>first wrap one&#8217;s head around their workings<\/strong>. The pie chart on the other hand, with all its shortcomings, is a very familiar device for showing shares.<\/li>\n<li>The dots make it <strong>hard to precisely appreciate the shares<\/strong>. E.g., in the second infographic it&#8217;s not readily visible at all that the two white dots represent a quarter of all dots. In a (2D) pie chart, we can eyeball a quarter really quickly though. The infographics seemingly try to make up for this shortcoming by adding explicit coding of the percentages.<\/li>\n<li>The dots also give a (very likely untrue) <strong>impression of a discrete variable<\/strong>, as if the percentages of the four widgets can only vary by increments and decrements of 12.5%.<\/li>\n<li>Inexplicably, the first infographic <strong>uses a different orientation<\/strong> (counter-clockwise from the 9 o&#8217;clock position) from the three remaining infographics. Also, the 9 o&#8217;clock\u00a0origin seems like quite an arbitrary, non-obvious choice to me. Most intuitively, you would choose 12 o&#8217;clock, probably, mathematically, 3 o&#8217;clock.<\/li>\n<li>To me, the yellow dots are <strong>far more attention-grabbing<\/strong> than the white ones. Thus, at first glance I thought the yellow dots are data elements and the white dots are no-data. But it&#8217;s the other way around.<\/li>\n<li>The <strong>faux-analoge printing effect<\/strong> is pretty but confused me at first: It tricked me into thinking if the variable\u00a0appearance\u00a0of the dots encodes information (I&#8217;ll have to assume it doesn&#8217;t). I think this is due to the varying size of the white dots and the arbitrary overprinting of the yellow dots into the red background. Pretty, but a bit confusing in this instance.<\/li>\n<\/ul>\n<p>I won&#8217;t comment on the rest of the slide design and the trade-offs and choices made e.g. with regards to the relative size of the actual content. I\u00a0think these are partly personal taste and also that these choices have to be made with respect to the overall narrative, the wider slide deck design, the audience and the event and likely a few more factors.<\/p>\n<p>&nbsp;<\/p>\n<h3>Advice for public speaking beyond slide design<\/h3>\n<p>Much (most?) about public speaking is in the actual\u00a0<em>speaking<\/em> (duh!). Thus, I want to point out two good (and not nearly known-enough) pieces of advice by the German writer Kurt Tucholsky (1890\u20131935): <strong><em>Advice for making a bad speech<\/em><\/strong> and <em><strong>Advice for a good speaker<\/strong>.<\/em><\/p>\n<p><a href=\"http:\/\/www.wendelberger.biz\/news_files\/kurt_tucholskys_advice.php\">English translations of both texts can be found here<\/a>. From the second:<\/p>\n<blockquote><p>Main clauses. Main clauses. Main clauses.<\/p>\n<p>Clear concept in your head \u2014 as little as possible on paper.<\/p>\n<p>Give either facts or appeal to sentiment. Use either sling or harp. A speaker shouldn\u2019t be an encyclopaedia. People have one of those at home.<\/p>\n<p>(&#8230;)<\/p>\n<p>Do not strive for effects that are contradictory to your personality. A podium is an unforgiving thing \u2014 one is more naked than during a sunbath.<\/p><\/blockquote>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I have a Slideshare account that I use to publish slides of presentations I&#8217;ve held (if it&#8217;s okay to publish them, which is the case only very occasionally).\u00a0Sometimes Slideshare sends me e-mail news that I more often trash than skim.
