Overall it was quite well received. Aside from the usual omg does my voice really sound like that?? which is to be expected, a couple of thoughts on the business of giving presentations which were quite salient here:
- Talk slower and enunciate
- Gesture, but not too much
- Tailor sizing and colouring of visuals, depending on projection & audience size
I've reproduced the code which was used to create the figures made in R (including the bubble chart example, with code and data from FlowingData), which regrettably at the time I neglected to save. Here it is in a gist:
The visuals are also available on Slideshare.
Lessons learned: talk slower, always save your code, and Google stuff before starting - because somebody's probably already done it before you.
