sparklines – Draw­ing sparklines: in­tense, sim­ple, word­like graph­ics

Sparklines are in­tense, sim­ple, word­like graph­ics (so named by Ed­ward Tufte). In lieu of a more de­tailed in­tro­duc­tion, Pro­fes­sor Tufte's site has an early re­lease of a chap­ter on sparklines. A PHP im­ple­men­ta­tion may be found at SourceForge.
A sparkline can be added us­ing the sparkline en­vi­ron­ment. Also, you can add sparkling rect­an­gles for the me­dian and spe­cial sparkling dots in red or blue. The pack­age re­quires pdfla­tex; sparklines can­not ap­pear in a dvi file. The sparklines pack­age uses pgf, and does not work with pictex.
