 ## Why plot?
-The goal of research is to improve our understanding of the world, but that increase in knowledge is small if that understanding doesn't spread.

 ## Choices in analysis and presentation
-Producing a figure will often decide on the story you want to tell, or the pattern you wish to highlight in your data. You have to decide which variables in your data (group, treatment, location, time, amount)to map to the available visual dimensions (x-y-z position / colour / symbols / etc).

-Modern sources of data often present aditional problems, those of density and complexity, that require further choices relating to aggregation and ommission. All of these aspects require choices and this can force a certain interpretation on your audience, a limit what you can show.

 Interactivity gives the reader/user a chance to explore the data in ways a static (non-interactive) plot does not.  It can also help you and your collaborators understand your data better.
