Sparklines and Bullet Charts Oh My!
The number of tools, add-ins and routines to generate your own data visualisations seems to be evolving very quickly. I use the single little spark stats WordPress plug-in to keep track of post frequency on Randomosity. when I first was playing with sparklines, I downloaded a shareware version of Bissantz SparkMaker plug-in for excel and there was also a similar higher cost tool available from Microcharts. I know that Bissantz has been constantly tweaking his tools and they have become more powerful. They are nice tools and should command a payment. I certainly do not begrudge. Microcharts seem to have evolved even faster. I happened to be doing a little walkabout to see where things in the data viz arena were at and when I saw the latest Microcharts/Pro, have to admit to being floored.
I will have to try the latest versions and see how the evolutions actually empower the user. As with any such tool, knowing how to best harness the tool and be able to decide on what visualisation is most appropriate to the message still remains the key. I am reminded, most simplistically, of all the resumes written using Apple’s kidnap letter-like San Francisco font in 1984, simply because they could. Books such as Few’s ‘Information Dashboard Design’ or Niederman and Boyum’s ‘What the Number’s Say‘, are two useful tools to thoughtful data presentation.
Update: Note the revised Microcharts pricing that Andreas Flockermann forwarded as a comment. Like SparkMaker, there is a free version for educational and not for profit use. Hopefully appreciation of the value of these tools will incent users to upgrade to the Pro versions.
