I have recently started using the tufte-latex package for various science writing and, while I love the package generally, am dismayed that it does not include the ability to produce graphics (charts, sparklines, etc.) in the style of Tufte. While his typesetting is wonderful, it seems to me that the plots are the primary focus of his work.
Is there a readily available package that allows for easy production of Tufte-style plots? Perhaps using pgfplots or sageTeX?
The pgfplots package can do a lot of plotting stuff.
In contrast to the simpler sparkline package, it supports arbitrary input data - which might be given by some math expressions or table data (which might be interesting for statistical applications). It also comes with pgfplotstable which allows some automatic rounding of such tables.
In fact, I believe that I came across a solution by someone who produced pretty sparklines side-by-side using pgfplots and some table solution (looked pretty cool). If someone happens to know what I saw, this might be an interesting solution approach here (but I do not know where it is).
From my point of view, a usable solution for sparklines with pgfplots would need:
Here is the the output of an experiment this evening:

My idea is to define a macro \sparkline <coordinate input> ; which expects one of the different <coordinate input>s of pgfplots, as \addplot {rand}; or \addplot table (which are used above). I should note that in my case above, the space between {rand} and ; is mandatory (due to some expansion issue).
My idea is to use \baselineskip to determine the sparkline's dimensions (which, however, appears to cause problems inside of tabular!?).
The rest of the user interface is given by the options spark std min and spark std max which configure the gray background area.
Within this solution, all other things could be configured by means of styles.
fixed zerofill instead of fixed,fixed zerofill and showing the same start-and end coordinate in the texts).

I'd suggest you go with Christian Feuersänger answer but I'd also like to note that there's the path egreg mentioned in a comment.
There's the package called sparklines.
\documentclass{tufte-handout}
\usepackage{sparklines}
\begin{document}
A sparkline
\begin{sparkline}{10}
\sparkrectangle 0.3 0.8
\sparkdot 0.5 0.62 blue
\sparkdot 1 0.2 red
\spark 0.1 0.95
0.6 0.7
0.2 0.8 0.3 0.3 0.4 0.52 0.5 0.62
0.7 0.5 0.8 0.4 0.9 0.25 1 0.2 /
\end{sparkline}.
and another
\begin{sparkline}{4}
\sparkspike .083 .18
\sparkspike .25 .55
\sparkspike .417 1
\sparkspike .583 .62
\sparkspike .75 .42
\sparkspike .917 .5
\end{sparkline}.

R does rugplots nicely) and just includegraphics. After all, TeX doesn't specialise in graphics.

Although it appears that there aren't any readymade packages specifically for LaTeX, depending on which math/graphics package you use, there might be alternatives.
For example, the sagemath program provides a ready interface to LaTeX through it's sageTeX module and renders 2D plots with the Matplotlib library. Options passed on to plots that do not have meaning in Sage will be passed to Matplotlib so it is then possible to use packages like etframes to get tufte style plots. Though I only recently came across this package, I'll add more if I find them as I do research.
