DESCRIPTION:I'm practicing my talk for the upcoming EuroVis conference - p
 lease come along! I'm looking forwards to any form of feedback :)\n\n*Abst
 ract:*\nDiscussions between data analysts and colleagues or clients with n
 o statistical background are difficult\, as the analyst often has\nto teac
 h and explain their statistical and domain knowledge. We investigate work 
 practices of data analysts who collaborate\nwith non-experts\, and report 
 findings regarding types of analysis\, collaboration and availability of d
 ata. Based on these\, we have\ncreated a tool to enhance collaboration bet
 ween data analysts and their clients in the initial stages of the analytic
 al process.\nSketching time series data allows analysts to discuss expecta
 tions for later analysis. We propose function composition rather\nthan fre
 ehand sketching\, in order to structure the analyst-client conversation by
  independently expressing expected features in\nthe data. We evaluate the 
 usability of our prototype through two small studies\, and report on user 
 feedback for future iterations.
