Sparklines , also called word graphics , are used to graphically explain numbers in text in a space-saving manner . In the form of a highly miniaturized ( time series ) diagram , sparklines show the historical development of a numerical value and thus give it the context that is important for its interpretation . The concept was developed and named by Edward Tufte , a professor at Yale University .
The advantages of sparklines are:
- The graphics are built directly into the text flow.
- These are diagrams minimized to line height that visualize the texts and their statements.
- Large, space-consuming diagrams are not used.
