Sparklines are part of what’s considered the “first wave of data viz,” centered around the work of Edward Tufte, who emphasized clarity, simplicity, and direct one-to-one mapping of data points through the six principles outlined in his book The Visual Display of Quantitative Information. They are as follows:

  1. The representation of numbers, as physically measured on the surface of the graphic itself, should be directly proportional to the numerical quantities measured.

  3. Show data variation, not design variation. …

I know that I had promised to write about the “waterfall” chart as part of making a series on Getting Started: The What, Where, Why & How of Data Visualisation.

It’s almost the end of my post graduate program @ School of Inspired Leadership in Gurgaon

I had noticed this nondescript tennis court nearby 3 months back. Trying to become an earnest student, I became an erstwhile tennis player. Ahem, enough of maudlin !

I finally exhorted myself to become an earnest tennis player yet again, after almost 5 long years (Thanks for the inspiration from my mentor, Mr. Arun Kumar who plays golf !). Playing tennis is one thing which I have been missing for so long !
