Sparkline is a name proposed by Edward Tufte for "small, high resolution graphics embedded in a context of words, numbers, images"[1]. Edward Rolf Tufte (IPA /ËtÊf. ...
Tufte describes sparklines as "data-intense, design-simple, word-sized graphics"[1]. Whereas the typical chart is designed to show as much data as possible, and is set off from the flow of text, sparklines are intended to be succinct, memorable, and located where they are discussed. Their use inline usually means that they are about the same height as the surrounding text.

A sparkline is a small line graph designed to be used in-line within text to illustrate a time series; the concept was developed by data presentation guru Edward Tufte.
One advantage of sparklines' compactness is that several can be used together to allow at-a-glance comparison between a set of time series.
Sparklines are tangentially related to photography - they are used alongside images as a graphical design element in qualitative and quantitative analysis.
